Question

41. Which is/are not the correct variation of properties in NH2-, NH3, and NH4+
A) NH, <NH, < NH; -H-N-H bond angle
B) NH, <NH, <NH, - number of lone pairs on N atom
C) NH, <NH, <NH-N-H bond length
D) NH, <NH, < NH; - number of s and p orbitals used in hybridisation​

Answer 1

Answer:

B) NH, <NH, <NH, - number of lone pairs on N atom.

Explanation:

This is your answer.

Answer 2

Answer:

Concept:

The three-dimensional configuration of the atoms that make up a molecule is known as molecular geometry. In addition to bond lengths, bond angles, torsional angles, and any other geometrical factors that affect each atom's position, it also contains the molecule's overall structure. A substance's reactivity, polarity, phase of matter, colour, magnetism, and biological activity are only a few of the attributes that are influenced by its molecular geometry. It is possible to think of an atom's angles between bonds as roughly local and so transferrable features because they depend on the rest of the molecule only tangentially.

Given:

Which of the following variations in NH2-, NH3, and NH4+ characteristics is/are correct?

(A) NH−2<NH3<NH+4,(H-N−H) bond angle

(B) NH−2<NH3<NH+4 lone pairs on N - atom

(C) NH−2<NH3<NH+4(N−H) bond length

(D) NH−2<NH3<NH+4 number of s and p - orbitals used in hybridisation

Find:

find the correct option for the given question

Answer:

The correct options are B, C, D

B) NH, <NH, <NH, - number of lone pairs on N atom

Maximum number of lone pairs in is two.

C) NH, <NH, <NH-N-H bond length

The p-character inside the NH bond grows as the number of lone pairs does, which also lengthens the NH bond. Consequently, the proper sequence of bond length is NH2>NH3>NH+4(NH) bond length.

D) NH, <NH, < NH; - number of s and p orbitals used in hybridisation​

Because all three species are sp3 hybrids, d is untrue.
