Reaction Of Alkene

Question 1

Why?

Answer 1

• double bond have greater electron density than single bonds
• electron in pic bonds are accessible to approaching rxts as they are located abound and below the plane of double bond
• alkene involve reaction of electron-rich double pond with electron-poor rxts

Question 2

2 major types of reaction?

Answer 2

1. Catalytic hydrogenation

2. Oxidation-> alcohols, ketones, carboxylic acid

Question 3

What is polar reaction?

Answer 3

• unsymmetrical bond breaking or bond forming

- involving the donation of an electron pair from a nucleophile to an electrophile

Question 4

4 rules for the mechanism?

Answer 4

1. electrons move from Nu: to E
   - Nu: l.p or a multiple bond
   - E: accepts l.p as it has a positively charged atom/ atoms with partial positive charge
2. Nu: negatively charged or neutral
3. E- positive or neutral
4. octet rule must be obeyed
