Identify the correct statements about the hydrides.
(I) In saline hydrides oxidation state of hydrogen is +1
(II) $LaH$ is an example of interstitial hydride
(III) $NH_{3}, H_{2} O$ have the tendency to form hydrogen bonds
(IV)Electrolysis of molten sodium hydride liberates $H_{2}$ gas at cathode

Question

Identify the correct statements about the hydrides.
(I) In saline hydrides oxidation state of hydrogen is +1
(II)

LaH

is an example of interstitial hydride
(III)

NH_{3}, H_{2} O

have the tendency to form hydrogen bonds
(IV)Electrolysis of molten sodium hydride liberates

H_{2}

gas at cathode

Accepted Answer

Correct answer: D. (d) Statement (I) is incorrect because saline or ionic hydrides have the hydrogen atom in -1 oxidation state. Statement (IV) is incorrect because at cathode, reduction of Na^+to Na takes place while hydrogen gas is liberated at the anode.
