\backslash\phantom{.........}\\
\ce{C = O}\\
/\phantom{........}\\
\ce{R}\phantom{.........}
\end{array}\], the carbonyl carbon is joined to other atoms by ____________.

पर्याय

• two sigma and one pi bonds

• three sigma and one pi bonds

• one sigma and two pi bonds

• two sigma and two pi bonds

Answer 1

In the group \[\begin{array}{cc}
\ce{R'}\phantom{.........}\\
\backslash\phantom{.........}\\
\ce{C = O}\\
/\phantom{........}\\
\ce{R}\phantom{.........}
\end{array}\], the carbonyl carbon is joined to other atoms by three sigma and one pi bonds.

Explanation:

Three sigma bonds and one pi bond are formed by the carbonyl carbon.
