In the following three dimensional structure of \(\mathrm{CH}_4\), the bonds are labelled as \(W, X, Y\) and \(Z\). The bonds projecting out of the plane are:

A X,Y
B W, Z
C X, Z
D W, Y

Verified Solution

Answer & Solution

Correct Answer

(B) W, Z

Step-by-step Solution

Detailed explanation

The bonds that are projecting out of the plane are \(W\) and \(Z\). Here, normal lines \((-)\) always shows the groups, lying in the plane of the paper. Solid-wedge shows the bond projects out of the plane of paper and towards the observer. Dashed-wedge \((|||| \mid)\) also,…

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
