Electrolysis of potassium acetate yields .........

Which product is the major product in the photobromination of $2$-methylbutane?

How many types of carbon atoms are present in $2,2,3-$trimethylpentane?

Complete the following reactions:
$(1)$ $CH_3CH_2CH_2CH_2Cl + H_2 \xrightarrow{Zn, H^{+}}$
$(2)$ $CH_3CH_2CH_2CH_3 \xrightarrow[HCl, \Delta]{Anhy. AlCl_3}$

An alkane forms isomers if the number of carbon atoms is at least

$CH_3-CH_2-COO^{-} Na^{+} \xrightarrow[\Delta]{NaOH + ?} CH_3-CH_3 + Na_2CO_3$. Consider the above reaction and identify the missing reagent/chemical.
