Give the structural molecular formula for 1,2-dimethyl pentane
The structural molecular formula for 1,2-dimethyl pentane is C7H16.
To determine the structural molecular formula for 1,2-dimethyl pentane, we first need to understand the basic structure of pentane, which is a straight-chain hydrocarbon with five carbon atoms.
The molecular formula for pentane is C5H12.
To indicate that it is 1,2-dimethyl pentane, we need to include two methyl groups (CH3) on the second carbon atom of the pentane chain.
So, the structural molecular formula for 1,2-dimethyl pentane is:
CH3-CH(CH3)-CH2-CH2-CH3
