The stabilization of carbocations by cyclopropyl substituents results from the interaction of the cyclopropyl bonding orbitals with the vacant carbon p-orbitals.
Electrons in these orbitals are relatively at higher energy than normal sigma electrons and are therefore particularly effective in interacting with the vacant p-orbital of the carbocation. This interaction imposes a stereoelectronic prefernce for the bisected conformation of the cyclopropylmethyl Cation in comparison to the perpendicular conformation. Only the bisected conformation aligns the cyclopropyl C-C orbitals for effective overlap.
THIS IS A SPECIAL CASES IN ORGANIC CHEMISTRY AND MOST IMPORTANT ALSO . "
AND THAT IS ALSO CALLED AS BIND BIND CONJUGATION .
SO, DUE TO THAT TRICYCLOPROPYL METHYL ARE MORE STABLE .
HOPE IT CLEARS YOUR DOUBT
ALL THE BEST ..
