• B. 2, 3, 5- Trimethyl hexane
• C. 1,1- Dimethyl 2, 4- dimethyl pentane
• D. 4- Methyl, 2- propyl butane

Answer 1

The correct option is B

2, 3, 5- Trimethyl hexane

Let us begin by numbering the longest chain. No matter which outer carbon we start with, the longest chain is 6 carbons long.

There are three methyl substituents. One is at carbon number 2, another one is at carbon number 3 and another one is at carbon number 5. Therefore the name of the given compound is 2, 3, 5- Trimethyl hexane.
