PART - 2 CH - 9 Hydrocarbons — Chemistry STD 11 Science — Question

Which quantum number is not derived from Schrodinger wave equation?

How many radial and angular nodes are present in 2p-orbital.

1. What do you mean by sink? Give one example.
2. What is the sink for hydrocarbons and why?

Give two examples of interstitial hydrides.

Using s, p, d notations, describe the orbital with the following quantum numbers.
n = 3; l = 1.

Although very useful in a large number of cases, the octet rule has many exceptions. Give two examples to support this statement.

Arrange C-C, Ge-Ge, Si-Si, Sn-Sn in decreasing order of bond energy.

Electron gain enthalpy usually becomes less negative from top to bottom in a group.
Is there any exception to this generalisation? Comment.

Refer to the periodic table given in your book and now answer the following questions:
Select the possible non metals that can show disproportionation reaction.
