The major product formed in the following reaction is
$1,2-dichloro-3-methyl-5-nitrocyclopentane$ $\xrightarrow[{Heat}]{{NaOCH_3(1 \ eq.)}}$ ?

Given below are two statements:
Statement $I$: $(Et)_2N-CH_2CH_2Cl$ will undergo alkaline hydrolysis at a faster rate than $(Et)_2CH-CH_2CH_2Cl$.
Statement $II$: Intramolecular substitution takes place first by involving the lone pair of electrons on nitrogen.
In the light of the above statements,choose the most appropriate answer from the options given below:

Which of the following expressions is representative of the rate law for a $S_{N}2$ reaction?

What do you mean by dehydrohalogenation?

Elimination reactions (especially $\beta$-elimination) are as common as the nucleophilic substitution reaction in the case of alkyl halides. Specify the reagents used in both cases.
