Molecular formula of amyl alcohol is
1 \({C_7}{H_{14}}O\)
2 \({C_6}{H_{13}}O\)
3 \({C_5}{H_{12}}O\)
4 \({C_5}{H_{10}}O\)
Explanation:
Amyl denotes the straight chain of pentyl radical \(\left(- C _5 H _{11}\right)\). Amyl alcohol has an \(- OH\) group with pentyl radical. Hence, the formula is \(C _5 H _{12} O\).

Carbolic acid is
1 Phenol
2 Phenyl benzoate
3 Phenyl acetate
4 Salol
Explanation:
(a) \( 5\) \(\%\) aqueous solution of phenol at room temperature is called as carbolic acid.
Ethanol is a colorless, volatile liquid with a characteristic smell. It is also highly flammable. Ethanol is a simple alcohol with two carbon atoms and is represented by the chemical formula \(CH _3 CH _2 OH\). Absolute alcohol is a liquid alcohol solution which contains almost more than \(99 \%\) pure alcohol (ethyl alcohol) by weight. It is an important constituent of alcoholic beverages. Alcohol is prepared by the fermentation of sugar through petrochemical processes or by yeast. The alcohol obtained through this method contains some amount of water and it is removed by adding some dry slat. The dry salt absorbs the water content of the ethanol solution as it passes through and we obtain a pure alcohol, \(95 \%\) alcohol \(+5 \%\) water solution is known as rectified alcohol. It is a highly concentrated solution of ethanol. \(95 \%\) ethanol \(+5 \%\) methanol is known as denatured alcohol prepared by adding methanol to anhydrous ethanol. Pure alcohol prepared is denatured.
Amyl denotes the straight chain of pentyl radical \(\left(- C _5 H _{11}\right)\). Amyl alcohol has an \(- OH\) group with pentyl radical. Hence, the formula is \(C _5 H _{12} O\).
