3. | Use of a catalyst such as iron oxide mixed with small amounts of K2O and Al2O3 |
4. | All of the above |
Assertion (A): | Bond angle in PH4+ is higher than that in PH3 |
Reason (R): | Lone pair-bond pair repulsion is stronger in PH3 than bond pair-bond pair repulsion in PH4+ . |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |

4. | (A) is false but (R) is true. |
Assertion (A): | When PCl5 is heated then PCl3 and Cl2 are obtained as products. |
Reason (R): | PCl5 gives POCl3 with water. |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
