what is important while doing organic synthesis? - - using starting materials that are safe and non/low toxic - using reactions w a high atom economy/percentage yield - reducing waste + increasing efficiency - minimising solvent use - as they can often be flammable/toxic alkane to halogenoalkane - X2, UV light halogenoalkane to alkene - KOH, ethanol, reflux alkene to halogenoalkane - HX, 25 degrees alkene to dibromoalkane - Br2, 25 degrees halogenoalkane to primary amine - excess ethano...

What are the 5 steps in the Scientific Method? - Answer 1. Identify a problem or pose a question based on an observation. 2. Formulate a hypotheses. 3. Conduct experiments or tests the hypotheses. 4. Observe and record the results. 5. Draw a conclusion (was the hypothesis correct?). * peer review is also important.

An organism with chloroplasts in its cells is probably. a. a heterotroph b. an autotroph c. an herbivore d. a primary consumer B: Organisms that have chloroplasts in their cells carry on photosynthesis and are therefore autotrophs. Autotrophs make their own food. What property of water allows someone to fill a glass slightly above the rim without the water flowing over? a. specific gravity b. capillarity c. opacity d. surface tension D: Water molecules are polar. Due to the fact that ...
