Position isomerism along a carbon chain
What Position isomerism along a carbon chain means in Chemistry A-Level, as defined for OCR.
Definition of Position isomerism along a carbon chain
Check what you remember
Read the wording for your board, then hide it and explain Position isomerism along a carbon chain in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Substitution can occur at more than one carbon along a carbon chain, so a longer alkane yields structural isomers such as 1-chloropropane and 2-chloropropane.
