Answer:
R-group
Explanation:
The function groups in an alcohol and amine are R-OH and R-NHâ‚‚ respectively, where R is any alkyl group. The alkyl group can be polar, nonpolar, hydrophilic, hydrophobic, acidic or basic. The chemistry of the R group will influence the overall chemistry of the alcohol and the amine. Also the size of the R group is critical as the large the size or volume of the R the greater will be the steric hindrance and vice versa. Steric hindrance plays a critical role in the reaction mechanisms of alcohols and amines.
