Question
Which one of the statements about $$HO{H_2}CCH\left( {OH} \right)CHO$$ is not correct? It
A.
is an isomer of 1, 3-dihydroxypropanone
B.
contains a tertiary alcoholic group
C.
has the same empirical formula as glucose
D.
can show optical isomerism
Answer :
contains a tertiary alcoholic group
Solution :
\[\underset{\begin{smallmatrix}
|\,\,\,\, \\
\,\,\,\,\,\,C{{H}_{2}}OH
\end{smallmatrix}}{\overset{\begin{smallmatrix}
\,\,\,CHO \\
|\,\,\,\,
\end{smallmatrix}}{\mathop{H-C-OH}}}\,\]
It contains one primary and one secondary alcoholic group thus, option (B) is incorrect.
