Why is the melting point of carbon so much higher …

Hence more energy is required to break the covalent bonds between Carbon and Carbon is 1.54 pm as compared to that of Silicon Silicon which is longer and 186 pm. Also The Bond length between Carbon-Carbon atoms is lesser than that of Silicon making it harder to break the bonds. Hence Carbon has much higher melting point than that of Silicon.
