Answer to Question #286082 in General Chemistry for Mimi

Question

TRUE or FALSE

1. The organic starting materials for the preparation of an ester could be water and oxygen.

2. The reaction of water with alkene to produce an alcohol is a/an addition reaction.

3. When an alcohol is dehydrated it forms alkene.

4. Short chain alkanes are prepared through Catalytic cracking.

5. Two isomeric forms of a saturated hydrocarbon have the same molecular formula.

Answer 1

1. FALSE , Water and oxygen are not organic starting materials for preparation of ester

2. FALSE, The reaction of water with alkane to produce an alcohol is not addition reaction but hydration

3. TRUE, Dehydration of alcohols by heating alcohols in presence of a strong acid yields alkene

4. TRUE, Short chain alkanes are produced through catalytic cracking of long chains hydrocarbons.

5. TRUE, Two isomeric forms of a saturated hydrocarbon have the same molecular formula.
