Question
How many asymmetric centers are present in a molecule of 2,4,6-trimethylheptane?
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?
