Q

What is the difference between optical and geometric isomers?

A

Optical isomers/Enantiomers have a chiral center, cannot be super imposed of their mirror image and rotate PPL (plane polarised light) where as Geometric isomers contain a double bond and do not rotate PPL

Q

What makes the melting/boiling point of hydrocarbons increase?

A 
More Symmetric.
More Polar.
Has hydrogen bonding.
Molecular weight.
Even number of carbons.
Tighter packing.
17
Q

What are some examples of low and high boiling points for common hydrocarbons?

A

Alkanes, enes and ynes have lower boiling points then alcohols due to H bonding. Carboxylic is even higher. Amides > Amines
