Q1.
Condensed formula --> states CH3 for methyl branches, CH2 for linear carbons R-CH2-R
then
total CH3 in the left side = 2
total CH3 in the right side = 3
The central carbon has:
H, 2 branches, Cl, therefore
the cabron which is bonded to 3 CH3- and the carbon branch is simply 4 (4 valence aqre already occupied)
(CH3)2CHCH(Cl)C(CH3)3
the best answer:
a) can't be since CH3 total count is 6, which is false
b) This is the best answer
c) incorrect, since the CH3 count is 4, not 5
d) incorrect, CH3 count is 2+ 2= 4, which is false, ti shoudl be 5
choose B
