The correct order of thermal stability for the given compounds is
(a)$\mathrm{TiMe}_{4}>\mathrm{Ti}\left(\mathrm{CH}_{2} \mathrm{CMe}_{3}\right)_{4}>\mathrm{TiEt}_{4}$
(b)$\mathrm{TiEt}_{4}>\mathrm{Ti}\left(\mathrm{CH}_{2} \mathrm{CMe}_{3}\right)_{4}>\mathrm{TiMe}_{4}$
(c)$\mathrm{TiMe}_{4}>\mathrm{TiEt}_{4}>\mathrm{Ti}\left(\mathrm{CH}_{2} \mathrm{CMe}_{3}\right)_{4}$
(d)$\mathrm{Ti}\left(\mathrm{CH}_{2} \mathrm{CMe}_{3}\right)_{4}>\mathrm{TiMe}_{4}>\mathrm{TiEt}_{4}$
Answer
Answer: D ✓ checked by 4AB · confidence high
Explanation
Neopentyl (no β-H, bulky) is most stable, then methyl; ethyl decomposes by β-elimination (d).
