hoàn thành chuỗi propan->metan->axetilen->vinylaxetilen->butan->propilen->propilenglycol giúp mình với ạ :((

$C_3H_8 \buildrel{{\text{cracking}}}\over\to CH_4+ C_2H_4$ 

$2CH_4 \buildrel{{1500^oC}}\over\to C_2H_2+ 3H_2$

$2CH\equiv CH \buildrel{{xt, t^o}}\over\to CH\equiv C-CH=CH_2$

$CH\equiv C-CH=CH_2+ 3H_2 \buildrel{{Ni, t^o}}\over\to CH_3-[CH_2]_2-CH_3$

$C_4H_{10} \buildrel{{\text{cracking}}}\over\to C_3H_6+ CH_4$

$3C_3H_6+ 2KMnO_4+ 4H_2O \to 3CH_3-CHOH-CH_2OH + 2MnO_2+ 2KOH$
