What are structual isomers? Write the possible carbon skeletons of butane (C⁴H¹⁰).
Answers
Answer:
Hint: Structural isomers are those which have the same molecular formula but different bonding patterns and atomic organization. Butane is an organic compound with 4 carbon atoms attached with single bonds. So, just see the number of arrangements that can be formed by butane.
Complete step by step answer:
-Isomers are molecules which have identical chemical formulas but distinct arrangements of atoms in space. The two main forms of isomerism are:
-structural isomerism or constitutional isomerism in which bonds differ
-stereoisomerism or spatial isomerism where orientation of atoms differs.
-structural isomers are those isomers where the molecular formula remains same, only their bonding patterns and atomic organisation differs.
-Butane is a 4 carbon organic compound and since the suffix is –ane we can say that there are only single bonds (it is a saturated molecule). There are no double or triple bonds (it is not unsaturated).
-It’s molecular formula is: C4H10.
-Butane can form 2 structural isomers: 1) n-butane
2) isobutene (2-methylpropane)
1) n-butane or butane: In this first arrangement all the 4 carbon atoms are arranged one after the other to form a single chain with no branching. It is known as n-butane and its molecular formula is C4H10
