Red hot carbon will remove oxygen from t...

Red hot carbon will remove oxygen from the oxide 40 and BO but not from MO, while B will remove oxygen from 40. The activity of metals A, B and M in decreasing order is

A

`A gt B gt M`

B

`B gt A gt M `

C

`M gt B gt A`

D

`M gt A gt B`

Text Solution

Verified by Experts

The correct Answer is:
C
Carbon removes oxygen from 10 and BO, C is better reducing agent than A and B, B removes oxygen from AO, B is better reducing agent than A. Better reducing means more active. Hence, the correct order is M > C > B > 4.
