Question

Which of the following is the strongest $-I$ group?

• A. $-\stackrel{+}{N}(C{H}_3{)}_3$
• B. $-\stackrel{+}{N}{H}_3$
• C. $-\stackrel{+}{S}(C{H}_3{)}_2$
• D. $-F$

Answer 1

The correct option is A $-\stackrel{+}{N}(C{H}_3{)}_3$

Answer is option A i.e; $-\stackrel{+}{N}(C{H}_3{)}_3$.

In $-I$ group, the priority of $-\stackrel{+}{N}(C{H}_3{)}_3$ is greater than other group.
