The stability of adducts $\mathrm{H}_{3} \mathrm{B} \cdot \mathrm{PF}_{3}, \mathrm{H}_{3} \mathrm{B} \cdot \mathrm{NMe}_{3}, \mathrm{H}_{3} \mathrm{B} \cdot \mathrm{CO}, \mathrm{H}_{3} \mathrm{B} \cdot \mathrm{OMe}_{2}$ follows the order
(a)$\mathrm{H}_{3} \mathrm{B} \cdot \mathrm{OMe}_{2}<\mathrm{H}_{3} \mathrm{B} \cdot \mathrm{CO}<\mathrm{H}_{3} \mathrm{B} \cdot \mathrm{PF}_{3}<\mathrm{H}_{3} \mathrm{B} \cdot \mathrm{NMe}_{3}$
(b)$\mathrm{H}_{3} \mathrm{B} \cdot \mathrm{PF}_{3}<\mathrm{H}_{3} \mathrm{B} \cdot \mathrm{CO}<\mathrm{H}_{3} \mathrm{B} \cdot \mathrm{NMe}_{3}<\mathrm{H}_{3} \mathrm{B} \cdot \mathrm{OMe}_{2}$
(c)$\mathrm{H}_{3} \mathrm{B} \cdot \mathrm{CO}<\mathrm{H}_{3} \mathrm{B} \cdot \mathrm{PF}_{3}<\mathrm{H}_{3} \mathrm{B} \cdot \mathrm{NMe}_{3}<\mathrm{H}_{3} \mathrm{B} \cdot \mathrm{OMe}_{2}$
(d)$\mathrm{H}_{3} \mathrm{B} \cdot \mathrm{PF}_{3}<\mathrm{H}_{3} \mathrm{B} \cdot \mathrm{CO}<\mathrm{H}_{3} \mathrm{B} \cdot \mathrm{OMe}_{2}<\mathrm{H}_{3} \mathrm{B} \cdot \mathrm{NMe}_{3}$
