Question

Nucleus seeking species among the following is
(1) H2O
(2) R2NH
(3) R3N
(4) All of these​

Answer 1

Answer:

Nucleus seeking species among the following is

R3N

Answer 2

The correct option is 4.

• The species which contain a negative charge or lone pair of electrons are the nucleus seeking species.
• Here water contains two lone pair electrons so, it is a nucleus seeking species.
• $R_2NH$ has two +I groups which donate electrons to N and increase the electron density of N and the species act as nucleus seeking species.
• $R_3N$ has 3 +I groups which donate electrons to N and increase the electron density of N and the species act as nucleus seeking species.
