Bond angle helps us in

The amount of energy required to break one mole of bonds of a particular type between two atoms in a gaseous state is called

H.O.H bond angle in water is

For N₂, bond order is

The product of the magnitude of the charge and the distance between the centres of positive and negative charge is called

the valence shell electron pair repulsion (vsepr) theory helps in the

In the formation of hydrogen molecule, overlapping of atomic orbitals occur  which results in the pairing of electrons. These are:

$$PCl_5$$ has a shape of trigonal bipyramid whereas $$IF_5$$ has the shape of a square pyramid. It is due to:

Which of the following molecule has a dipole moment ?

Electron pairs occupy localised orbitals. Their orbitals are oriented in such a way that the repulsion between electron clouds becomes:

Arrange the following compounds in increasing dipole moment.
toluene $$(I)$$, $$m$$-chlorobenzene $$(II)$$, $$o$$-dichlorobenzene $$(III)$$, $$p$$-dichlorobenzene $$(IV)$$

The number of bonding pairs electron  $$(X)$$ and lone pairs electron $$(Y)$$ around the central atom in the $${I}^-_3$$ ion are $$X +Y$$:

Geometrical configuration of $$BF_3$$ and $$NF_3$$ molecules is:

Bond length can be calculated by merely adding covalent bond radii which are $$H$$ = 0.28 $$\mathring {A}$$, $$N$$ = 0.70 $$\mathring {A}$$, $$O$$ = 0.66 $$\mathring {A}$$, $$Cl$$ = 0.99 $$\mathring {A}$$, $$(C=)$$=0.67$$\mathring {A}$$, (C$$\equiv $$)=0.61 $$\mathring {A}$$, (N$$\equiv $$)= 0.55 $$\mathring {A}$$ and $$(C-) = 0.77A^o$$. Calculate bond lengths in $$NH_{3}$$ :

Which one would better represent bonding in the molecule $$HNO$$?
I : $$H - \ddot{N} = \ddot{O}:$$  and II : $$H - \ddot{O} = \underset{\cdot\cdot}{\ddot{N}}$$

True structure is predicted by :

In which compound, are the bonds most polar?
