Which of the following statement is incorrect about diamond .
a) All the carbon atoms in diamond is `sp^(3)`hybridized.
b) Bad conductors of electricity due to odd electron on each carbon atom
c) It has three dimensional polymeric structure .
d) Very hard compared to graphite

Graphite has a two dimensional sheet-like structure in which each carbon atom is sp^3 hybridized .

How many of the following statements are correct regarding allotropes of carbon: (a) Graphite is not a good conductor of electicity in perpendicular direction of layers at ordinary temperatures. (b) Coke is the impure form of carbon. ( c) Anthracite is the purest form of carbon. (d) Buckminister fullerence contains 12 five membered rings and 20 six-membered rings. (e) Diamond is a good conductor of heat. (f) Graphite is diamagnetic in nature. (g) Graphite is thermodynamically more stable than diamond

Assertion : Among the carbon allotropes, diamond is an insulater, wherea, graphite is a good conductor of electricity. Reason : Hybridization of carbon in diamond and graphite are sp^3 and sp^2 , respectively.

Allotropes of carbon: There are three forms of carbon. i.e., diamond, graphite and fullerene which exxist in crystalline form. Graphite and diamond occur in nature. The structure of diamond is tetrahedral with sp^(3) hybridisation and diamond exist in 3-D netowrk solid. in graphite, carbon is sp^(2) hybridised. each carbon linked to other carbon linked to other carbon atom forms hexagonal ring. it has a layered structure. diamond and graphite are purest form of carbon. Fullerene constitute a new family of carbon allotropes. Consisting of large spheroidal molecule of compound with general formula C_(2n) . common fullerene C_(6),C_(70) , contain 5 and 6 membered rings. Q. Which of the following statement is incorrect for graphite?

Which of the following structure contains sp - hybridized carbon atoms? underset(I)(HC-=CH)" " underset(II)(H_2C=C=CH_2)

Assertion: C_(3)O_(2) has linear structure. Reason: Each carbon atom in C_(3)O_(2) in sp -hydridized.

Assertion: C_(3)O_(2) has linear structure. Reason: Each carbon atom in C_(3)O_(2) in sp -hydridized.

Diamond is hard and a bad conductor of electricity while graphite is soft and a good conductor of electricity. Explain. State the hybridization of carbon in both substances.

Which of the following given statements is/are incorrect- (a) there are five unpaired electrons in (n-1)d subshell of Fe^(3+) , (b) the number of nodal planes in 4d_(xy) orbital is one, (c) in Ag atom 23 electrons have a spin of one type and 24 of the opposite type

Which of the following statements are correct? (I) N_(2)H_(4) is pyramidal about each N atom. (II) NH_(2)OH is pyramidal about the N atom and bent about the O atom. (III) CH_(3)COCl is trigonal planar about the carbon atom ( attached to O and Cl).
