WebFeb 24, 2024 · With less bulky alkyl groups, dimerization occurs and one of the distinguishing features of alkyl bridge is the small Al-C-Al angle, which is ~ 75°. The 3c,2e bonds are very weak and tend to dissociate in the pure liquid which increases with increase in the bulkiness of the alkyl group. \[\ce{Al2(CH3)6 <=> 2Al(CH3)3} \nonumber \] K= 1.52 … http://web.mit.edu/5.03/www/readings/electron_deficient/electron_deficient_b2h6.pdf
