Question

Which of the silanes are formed by the reactions of $Mg_2Si + H_2SO_4 \longrightarrow$
A. $Si_4H_{10}$
B. $Si_3H_8$
C. $Si_5H_{10}$
D. $Si_6H_{14}$
E. $Si_7H_9$
Choose the correct answer from the options given below :

• A. B, C, E only
• B. A, D only
• C. B, D, E only
• D. A, B, D only

Hint:

Silanes follow the general formula $Si_nH_{2n+2}$, exactly like alkanes. Any formula that deviates from this (like $Si_5H_{10}$ or $Si_7H_9$) in introductory inorganic chemistry is usually incorrect or represents a much rarer cyclic variant not formed via simple $Mg_2Si$ hydrolysis.

Answer 1

The Correct Option is D
