CO is an unsaturated compound because all the valencies of carbon are not satisfied and forms addition compounds e.g. It forms carbonyl sulphide (COS ) with sulphur, carbonyl chloride ( phosgene `COCl_(2)` ) with chlorine, sodium formate with NaOH , methyl alcohol with `H_(2)` in the presence of `ZnO//Cr_(2)O` as catalyst)
`A overset("Red hot coke")(rarr)CO overset(Cl_(2))(rarr)C overset(H_(2)O)(rarr)2HCl+A`. The compounds A and C are

A

`CO_(2),COCl_(2)`

B

`CO,COCl_(2)`

C

`C,CO_(2)`

D

`CO_(2),CO`

Text Solution

Verified by Experts

The correct Answer is:
A
`CO_(2) overset("Red hot coke")(rarr)CO overset(Cl_(2))(rarr)`
`COCl_(2)overset(H_(2)O)(rarr) 2HCl + CO_(2)uarr`
`A = CO_(2)` carbodioxide
`C = COCl_(2)` Phosgene
