1. Examples of how organohalide compounds are used by humans - - have been found in marine life (algae, mollusks, sponges, etc.), bc they metabolize the high concentrations of inorganic chlorides and bromides that are found in the seas. - Industrially, organohalides find uses as solvents, insecticides, herbicides, cleaning fluids, fire retardants, and refrigerants, among others. - In medicinal use, many organohalides are used as inhaled anesthetics and disinfectants. - The compound know...

Steric Bulk - Structural substitution surrounding any carbon atom that bears a halogen. Methyl, primary, secondary, tertiary. Primary Alkyl Halide - Only on e carbon is directly attached to the carbon bearing the halogen. Secondary Alkyl Halid - Two carbons directly attached to the carbon ring bearing the halogen Tertiary Alkyl Halide - Three carbons are directly attached to the carbon bearing the halogen Methyl halide - Only hydrogen atoms attached to the carbon bearing the halogen X ...

The nucleophile in an SN2 reaction approaches the alkyl halide from? A) Anywhere, is does not matter. B) The same side of the carbon atom that the halide atom is attached to. C) The backside of the carbon-halide bond. D) The side of the carbon-halide bond. E) The top of the carbon-halide bond. - C) The backsid...

Organic Chemistry - the study of hydrocarbons and their derivatives hydrocarbon - compounds containing only carbon and hydrogen atoms hydrocarbon derivative - hydrocarbons containing atoms of at least one other element saturated hydrocarbon - all carbon-carbon bonds in molecules are single bonds Alkanes - a saturated hydrocarbon that is acyclic (does not have a ring structure) structural formula - 2 dimensional representation that shows how the various atoms in a molecule are bonded to ...

In the Sⁿ1 reaction (2-chlorobutane, 2-chloro-1-butene, or 3-chloro-1- butene) is the most reactive R-X. - 3-chloro-1-butene The energy required for an electronic transition across HOMO-LOMO gap is (directly, additionally, or inversely) proportional to the wavelength of light absorbed for that transition and shifted to (shorter, longer, or the same) wavelength for more conjugated molecules. - inversely, longer UV light excites an (n to pi*, sigma to sigma*, sigma* to sigma, pi* to pi, or...

Which type of atrioventricular (AV) block best describes this rhythm? - Second degree atrioventricular (AV) block type I To properly ventilate a patient with a perfusing rhythm, how often do you squeeze the bag? - Once every 5 to 6 seconds In addition to clinical assessment, which is the most reliable method to confirm and monitor correct placement of an endotracheal (ET) tube? - Continuous waveform capnography You are caring for a patient with a suspected stroke whose symptoms started 2 h...

When using a pocket mask, the rescuer would be positioned at the side of the victim. - True The rescuer uses the victim's chin as the guide to correctly position the pocket mask. - False When giving breaths to a victim by using a pocket mask, the rescuer would deliver each breath over 2 seconds and with just enough force to make the chest rise. - False When should the rescuer operating the AED clear the victim? - The AED operator clears the victim before rhythm analysis and then clears the...

For an unwitnessed cardiac arrest, what should you do after determining unresponsiveness and there is no breathing and no pulse? A) shout for help B) perform high quality CPR for 2 minutes C) provide rescue breaths D) activate the emergency response system - B) perform high quality CPR for 2 minutes The appropriate rate for compressions for children is 100-120/min. What is the correct depth for children? A) approximately 2 inches (one third the AP diameter) B) approximately 3 inches (on...

1. How can you help prevent concussions? - Talking to students about ways to lower the chance for hits to the head. 2. What is the first thing you should do as a coach when one of your students has sustained a bump or blow to the head or body and isn't acting right? - Remove the student from play and look for signs and symptoms of a concussion. 3. In general, how long should the return to play process take for an student to complete? - A week or more. 4. Which of the following are sympt...

If the head coach receives a red unsporting conduct card they must remain seated during the remainder of the match. - true A single mascot and/or school name placed on the uniform sleeve may not exceed 4 x 4 inches or 3 x 5 inches. - false Changes to the rosters may be made until 2 minutes remain on the prematch clock without penalty. - false Failure to submit a roster to the second referee at the prematch conference results in an administrative yellow card (unnecessary delay) at the star...
