With reference to the structure of the two crystalline allotropes of carbon, state why diamond is inert or unreactive while graphite in comparably more reactive,

What are allotropes? Sketch the structure of two allotropes of carbon namely diamond and graphite.

Name two crystalline and four amorphous allotropes of carbon

Compare the structure of the crystal of diamond graphite with special reference to the reason for diamond being the hardest natural substance while graphite one of the softest. Compare the electrical & thermal conductivity of the two crystalline allotropes of carbon.

What is the hybrid state of carbon in ethyne, graphite and diamond ?

State true or false Diamond is a crystalline form of carbon which is good conductor of electricity.

Compare the structure of diamond and graphite ?

Elemental carbon appears in many structural forms or allotropes . Three of these formssare crystalline -diamond ,graphite and the recentluy discovered fullerne (bucky ball ) -while more than 40 others including coke and carbon black ae amorphous . Now there seems to be set afourth crystalline allotrope of carbon. reported in 1995 by Lagow at the University of Texas . Structures fodifferentallotropes of carbon have been compared . Which represents incorrect comparison ?

Assertion : Diamond and graphite do not have the same crystal structure. Reason : Diamond is crystalline while graphite is amorphous.

Elemental carbon appears in many structural forms or allotropes . Three of these forms are crystalline -diamond ,graphite and the recently discovered fullerene (bucky ball ) -while more than 40 others including coke and carbon black are amorphous . Now there seems to be set as fourth crystalline allotrope of carbon. reported in 1995 by Lagow at the University of Texas . Newly discovered allotrope of carbon has the form :

The electronegativity of nitrogen and chlorine is 3.0 Why nitrogen is inert at room temperature , while chlorine is very reactive?
