Question

Which one of the following compounds will liberate CO₂, when treated with NaHCO₃?

Options

• \[\ce{(CH3)3 \overset{⊕}{N}HC\overset{⊖}{l}}\]

• \[\ce{(CH3)4 \overset{⊕}{N}\overset{⊖}{O}H}\]

• \[\begin{array}{cc}\ce{O}\\||\\\ce{CH3 - C - NH2}\end{array}\]

• \[\ce{CH3NH2}\]

Answer 1

\[\ce{(CH3)3 \overset{⊕}{N}HC\overset{⊖}{l}}\]

Explanation:

\[\begin{array}{cc}
\ce{(CH3)\overset{⊕}{N}HCl^⊖ + NaHCO3 -> H2CO3 + (CH3)3 N + NaCl}\\
\phantom{....}\downarrow\\
\phantom{....}\ce{CO2 + H2O}
\end{array}\]
