Write he IUPAC name of the following compound: `CH_(3)-O-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-CH_(3)`

`CH_(3)-CH_(2)-Br` because it is a primary alkyl halide and offers less steric hindrance to the attacking nucleophile as compared to the other alkyl halide which is of tertiary nature.

(i). `underset("2,3-Dimethylbutane")(CH_(3)-underset(CH_(3))underset(|)(C)H-underset(CH_(3))underset(|)(C)H-CH_(3))` (ii). `underset("Elhyl isocyanide")(CH_(3)-CH_(2)-N underset(rarr)(=)C)`

Correct Answer - A It is the correct IUPAC

Correct Answer - B `CH_(3)-underset(D)underset(|)((C)H-underset(CH_(3))underset(|)overset(**)(C)-CH_(3)` (tertiary free radical) is maximum. Stable due to hyperconfiguration.

Correct Answer - `CH_(2)=CHCH_(2)OH`

Correct Answer - D `I-undersetunderset(F)(|)overset(1)(C)=undersetunderset(Cl)(|)overset(2)(C)-overset(3)(C)-=overset(4)(C)-OCH_(3)`

Correct Answer - (a) `CH_(3)-overset(CH_(3))overset(|)(C )=O` , (b) `CH_(3)-underset(O)underset(||)(C )-underset(O)underset(||)(C )-CH_(3)`, (c ) `CH_(3)-COOH` , (d) `CH_(3)-overset(CH_(3))overset(|)(C )=O+CH_(3)-overset(O)overset(||)(C )-OH`
