In the above reaction X is

The major product of the following reaction is :

The major product of the following reaction is:
$$C_6H_5CH_2-\underset{\,\,\,Br}{\underset{|}{\overset{\,\,CH_3}{\overset{|}{C}}}}-CH_2-CH_3 \xrightarrow[C_2H_5OH]{C_2H_5ONa}$$

IUPAC name of $$(CH_3)_3CCl$$ is:

The general formula of alkyl halides is:

When $$Me_{3}C - O - CH_{3}$$ react with excess of $$HI$$ gives $$CH_{3}I$$ and $$Me_{3}CI$$. It follows the type of mechanism is:

Acetaldehyde undergoes aldol condensation giving $$\beta$$- hydroxyl carbonyl compound,which on dehydration in basic medium giving $$\alpha,\beta$$ unsaturated carbonyl compound,this dehydration in basic medium is an example for
