Which of the following are benzylic alcohols?
What is the structure and IUPAC name of glycerol?
Glycerol is the trihydric alcohol. Structure of glycerol is
So, IUPAC name is $-$ propoan- 1, 2, 3-triol.
Write the IUPAC name of the following compounds.
The correct IUPAC name of the following compounds are given below
(a) 
IUPAC name $\to$ 3-ethyl-5-methylhexan-2, 4-diol.
IUPAC name $\rightarrow$ 1-methoxy-3-nitrocyclohexane.
Write the IUPAC name of the compound given below.
The IUPAC name of the compound given below is
3-methylpent-2-ene-1, 2-diol.
Name the factors responsible for the solubility of alcohols in water.
Solubility of alcohols in water depends upon the two factors.
(i) Hydrogen bonding Higher the extent of hydrogen bonding, higher is the solubility. The hydrogen group of alcohol form hydrogen bonding. Solubility increases with increase in the number of - OH groups in alcohols of comparable molecular masses.
(I) Compound (II) will form stronger H -bond due to two - OH group and hence has higher boiling point.
(ii) Size of alkyl/aryl group Higher the size of alkyl/aryl group (hydrocarbon part), lower is the extent of hydrogen bonding and lower is the solubility. Hence,
$$\mathrm{H}_3 \mathrm{C}-\mathrm{CH}_2-\mathrm{OH}>\mathrm{CH}_3 \mathrm{CH}_2-\mathrm{CH}_2 \mathrm{OH}>\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2-\mathrm{CH}_2 \mathrm{OH}$$
