Question

How many isomer each containing a phenyl ring are possible for c9h12

Answer 1

Answer:

THERE ARE 8 ISOMER

mark me as brainliest............

Answer 2

4 structural isomers each containing a phenyl ring are possible for C9H12.

• We know that a phenyl ring has the formula -C₆H₅.
• Since the isomers should have a phenyl ring, the carbon atoms that can take different positions is 9 - 6 = 3.
• Also, only 12 - 5 = 7 hydrogens are available to satisfy the valencies of 3 carbons.
• The carbons can also exist as individual methyl or ethyl group.
• There are 4 ways in which 3 carbons can be arranged. It is shown in the below attachment.
• 2 out of these 4 structural isomers can also exhibit positional isomerism by getting attached to ortho, meta, or para position.
