That is
incorrect. A chiral carbon must have four different groups;
this carbon has two hydrogens attached and therefore has
internal symmetry.
That is
incorrect. A chiral carbon must have four different groups;
this carbon has three hydrogens attached and therefore has
internal symmetry.
That is
incorrect. A chiral carbon must be sp3 and have
four different groups attached; this carbon is
sp2.
That is
correct!
That is
incorrect. A chiral carbon must have four different groups;
this carbon has a hydrogen, a methyl group and two identical
branches of the same ring, and therefore has internal
symmetry.
That is
incorrect. A chiral carbon must have four different groups;
this carbon has a hydrogen, a methyl group and two identical

That is
incorrect. A chiral carbon must have four different groups;
this carbon has a hydrogen and two methyl groups, and
therefore has internal symmetry.
That is
incorrect. A chiral carbon must have four different groups;
this carbon has a hydrogen and three branches of the same
ring system, and therefore has internal symmetry.
That is
incorrect. A chiral carbon must be sp3 and have
four different groups attached; this carbon is sp
hydridized.
The carbon
indicated is chiral since it is bonded to four different
groups; a hydrogen, a methyl group, the 2-phenylethyl group
and the CH2OH.
