What are the differences between aliphatic (including alkanes, alkenes,alkynes and cyclic compounds) aromatic hydrocarbons are. - ALIPHATIC Hydrocarbon: Non-aromatic -Alkanes & CycloAlkanes:single bonds; saturated:Contain only carbon and hydrogen & C-C & C-H single bonds -Alkenes:double bond(s) -Alkynes: triple bond(s) *alkenes and alkynes are unsaturated: at least one C-C double or triple bond(s) AROMATIC Hydrocarbon: benzene ring What is the trend in solubility and boiling point/mel...

AC-HPAT Chemistry Questions With Complete Solutions double-displacement reaction A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products Precipitate precipitate is an insoluble solid that emerges from a liquid solution. The emergence of the insoluble solid from so...
