Phenol can be distinguished from ethyl alcohol by all reagents except

Detailed Solution: Question 1

Phenol reacts with NaOH, doesn't give Bromine water test but alchohol give Bromine water test and don't react with NaOH as pKa of alchohol is more than that of H2O but Na reacts with both phenol and alchohol so Na doesn't distinguish phenol and alchohol. hence D is correct

If R is the Rydberg constant for hydrogen, then wave-number of the second line in the Lyman series is

Detailed Solution: Question 3

Option C is correct.

Wave-number = 1/λ = R(1/n12 - 1/n22).

For the second line of the Lyman series, the final level is n1 = 1 and the initial level is n2 = 3.

So, 1/λ = R[1/12 - 1/32] = R[1 - 1/9] = R × 8/9 = 8R/9.

Therefore the wave-number is 8R/9, corresponding to option C.

which of the following hybridisation occurs in the formation of methane molecule?

Detailed Solution: Question 5

In the formation of a methane molecule (CH₄):

  • The central carbon atom undergoes sp³ hybridisation.
  • One s orbital and three p orbitals of the carbon atom mix to form four equivalent sp³ hybrid orbitals.

Thus, sp³-hybridisation occurs in the methane molecule.
