MCQ
The most basic oxide of elements in group $14$ of the periodic table is
- A$SiO_2$
- B$GrO$
- C$SnO_2$
- ✓$PbO$
✓
Answer
Correct option: D.
$PbO$
d
in a group oxide strength is depemd upon the atomic size so most size is $Pb$ hence $Pb$ oxide is most oxide.

Lead also form an oxide $Pb _3 O _4$ which is a mixed oxide of $PbO$ and $PbO 2$. Among the monoxides, $CO$ is neutral, $GeO$ is basic while $SnO$ and $PbO$ are amphoteric.
In $CO_2$, $C$ is sp hybridised
