Petrol for aviation purpose must contain
straight chain hydrocarbons
aromatic hydrocabrons

IUPAC name of (CH3)3 CCl is
n-butyl chloride
3-chloro butane
2-chloro-2-methylpropane
t-butyl chloride
The isomerism that arises due to restricted bond rotation is
metamerism
optical isomerism

The only o p-directing group which is deactivating in nature is
-NH2
-OH
-X(halogens)
-R(alkyl groupd)
D.
-R(alkyl groupd)
-NH2, -OH and -R (alkyl groups) all are o/p- directing and they activates the benzene ring -(X) halogens are however o/p-directing but deactivate the benzene ring by withdrawing electrons fron the ring due to -I effect.
The IUPAC name of the following compound is
1, 2-dimethyl-2-butenol
3-methylpent-3-en-2-ol
3, 4-dimethyl-2-buten-4-ol
None of the above
