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
