Question

How many asymmetric centers are present in a molecule of 2,4,6-trimethylheptane?
Options
A 0
Correct Answer
B 1
C 2
D 3
Correct Answer

Option A is the correct answer.

Detailed Explanation

2,4,6-trimethylheptane (CH3-CH(CH3)-CH2-CH(CH3)-CH2-CH(CH3)-CH3) has no asymmetric centers. The carbons at positions 2, 4, and 6 each have two identical methyl groups, so they are not chiral.

Hint

Are any carbons attached to four different groups in this molecule?
