Assertion : B_2 H_6, Si_2 H_6 are said to have similar structure....

Assertion : B2H6,Si2H6\mathrm{B}_2 \mathrm{H}_6, \mathrm{Si}_2 \mathrm{H}_6 are said to have similar structure. Reason : They have same number of σ\sigma and π\pi bonds .Assertion : B_2 H_6, Si_2 H_6 are said to have similar structure. Reason : They have same number of σ and π bonds .

Options

  1. AIf both Assertion and Reason are true and Reason is the correct explanation of Assertion.
  2. BIf both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
  3. CIf Assertion is true but Reason is false.
  4. DIf Assertion is false but Reason is true.

Correct answer

D. If Assertion is false but Reason is true.

Step-by-step solution

B2H6\mathrm{B}_2 \mathrm{H}_6 is an electron deficient compound. B2H6\mathrm{B}_2 \mathrm{H}_6 contain some unusual bonds which are called as 2 -electron 3 -centre bonds. Assertion : B_2 H_6, Si_2 H_6 are said to have similar structure. Reason : They have same number of σ and π bonds .
