Name the following compounds (1) CH3C (CH3) 2COOH (2) CH2 (OH) CH2CH (OH) CH2CH3 (3) CICH2CH (C2H5) CH2CHO and what the last compound stereoisomerism

1. 2,2-dimethyl-propanoic acid

2. 1,3-pentanediol

3. 4-chloro-3-ethylbutanal

Explanation:

1. The carbon in the carboxyl group is assigned number 1 by convention then counted chronologically as you move outwardly in the longest chain of the acid. The two methyl groups therefore occur on the second carbon.

2. There are two hydroxyl group on two different carbons. Two hydroxyl groups mean it is not an alcohol but a diol.

3. The carbon in the carbonyl group is assigned number 1 by convention then the carbons are numbered in chronological order as you mvoe outwardly on the longest chain.
