II Write short and precise answer
8, 1, Draw the skeleral shactures for the farrowing molecumos.
\[
\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{Cl}
\]
\( \Rightarrow \)
21 Alcohols \( A, B \) and \( C \) are have the compostson \( C+H_{10} O \) arcohol'A' contain ototitn a branclied chain and win be ox aushude; molecures of alcohol' \( B \) ' contarn a linedt car an be ox;dized to a ketone and moleaules of arooh oxidized to nsther an wldhyle nor a lotane. Write tho Lewrs sthackure of these molecuces.
