The alkali metal halides (MX) are all high melting, colorless crystalline solids which can be conveniently prepared by the reaction of the appropriate ____ with aqueous hydrohalic acids (HX).

A

oxide

B

hydroxide

C

carbonate

D

all of these

Text Solution

Verified by Experts

The correct Answer is:
D
`M_(2)O+2HX to 2MX+H_(2)O`
`MOH +HX to MX+H_(2)O`
`M_(2)CO_(3)+2HXto 2MX+CO_(2)+H_(2)O`
where M is `Li to Cs " and " X is F to I`.
Moreover, alkali metals combine directly with halogens under suitable conditions forming corresponding halides.

Read the passage given below and answer the following questions: Aldehydes, ketones and carboxylic acids are few of the major classes of organic compounds containing carbonyl group. Aldehydes are prepared by dehydrogenation or controlled oxidation of primary alcohols and controlled or selective reduction of acyl halides. Ketones are prepared by oxidation of secondary alcohols and hydration of alkynes. Carboxylic acids are prepared by the oxidation of primary alcohols, aldehydes and alkenes by hydrolysis of nitriles and by treatment of Grignard reagents with carbon dioxide. Through which of the following reactions number of carbon atoms can be increased in the chain?
