How many stereocentres (sp3 carbons bearing four different groups) are present in $CH X_{3} - CH (OH) - CH (CH X_{3}) - CH (Br) - C (CH X_{3}) X_{2} - CH X_{2} - CH (Cl) - CH X_{3}$ ? Give the answer as an integer.

Numerical answer type, tolerance 0.5.

Answer: 4

Check each sp3 carbon. CH(OH), CH(CH3), CHBr and CHCl each carry four different groups. C(CH3)2 has two identical methyl groups and CH2 has two hydrogens, so neither qualifies. The count is 4.
