The figure above represents any of the four trihalides of nitrogen, $$NF_{3}, NCl_{3}, NBr_{3}$$, and $$NI_{3}$$, where the X represents the halogen atoms. Here is some additional information regarding the elements involved.

Element	Electronegativity	Atomic Radius
$$N$$	$$3.0$$	$$70 pm$$
$$F$$	$$4.0$$	$$64 pm$$
$$Cl$$	$$3.0$$	$$99 pm$$
$$Br$$	$$2.8$$	$$114 pm$$
$$I$$	$$2.5$$	$$133 pm$$

Of the four nitrogen trihalides, only one is not a molecular dipole. Which one is the nonpolar molecule, and why is it nonpolar?

If element $$Mn^{y+}$$ has spin only magnetic moment 1.732 BM, then:

Dipole moment of $$CH_2 X_2 > CH_3 X, $$ then $$X$$ is :

The number of $$\sigma-bond$$ and $$\pi-bond$$ in $$HCP$$ are respectively:

The $$H-F$$ bond and the $$H-I$$ bond have different values of their bond polarity. Which of the following statements correctly identifies the bond that is more polar and gives the correct reason for this difference?

You have three solids. One is a metal; one is an ionic compound; one is a molecular/covalent compound. You test all three solid samples to identify their bonding.

In addition reactions of aldehydes, the carbonyl carbon atom changes from:

Correct sequence of repulsion is:
