Question
Select electrophiles out of the following:H+ Na+, Cl–, C2H5OH, AlCl3, SO3, CN–, CH3CH2+,CCl2, R-X.112. Arrange the following in increasing order of C – C bond strength:C2H6, C2H4, C2H2
Solution
-
Electrophiles are species that accept electron pairs. They are often positively charged or have a positive polarized bond. From the given list, the electrophiles are: H+, Na+, AlCl3, SO3, CH3CH2+, and CCl2.
-
The strength of the C-C bond depends on the type of bond. Single bonds are weaker than double bonds, which are weaker than triple bonds. Therefore, the order of increasing C-C bond strength is: C2H6 (single bond) < C2H4 (double bond) < C2H2 (triple bond).
