`CH_(3)` ,`NH_(3)` ,`H_(2)O` and `HF` are the examples of
O molecular hydrides
O metallic hydrides
O ionic hydrides
O non-stoichiometric hydrides

A : ScH_(2) is an example of ionic hydride. R : All metal forms ionic hydride.

Arrenge NH_(3), H_(2)O and CH_(4) in increasing bond angles.

Consider the following types of hydrides 1. Covalent hydride 2. Ionic hydride 3. Metallic hydride Which of these are formed by hydrogen?

The correct statements among (a) to (d) are (a). Saline hyddrides produces H_(2) gas when reaction with H_(2)O . (b). Reaction of LiAlH_(4) with BF_(3) leads to B_(2)H_(6) (c). PH_(3) and CH_(4) are electron rich and electron precise hydrides, respectively. (d). HF and CH_(4) are called as molecular hydrides.

Arrange H_(2)O, NH_(3) and CH_(4) in the decreasing order of bond angle.

Consider the molecules CH_(4),NH_(3) and H_(2)O which of the given statement is false ?

When the compounds HF, H_(2)O,NH_(3) , and CH_(4) are listed in order of increasing boiling point, which order is correct?
