Consider following statements: (I): In diamond, each carbon atom is linked tetrahedrally to four other carbon atoms by sp^(3) bonds. (II): Graphite has planar hexagonal layers of carbone atoms held together by weak Van der Waals forces. (III): Silicon exists only in diamonds structure due to its tendacy to form p pi- p pi bonds to itself. In this.

Conidier following statements : I : In diamond, each carbon atom is linked tetrahedrally to four other carbon atoms by sp_(3) bonds. II : Graphite has planer hexagonal layers of carbon atoms held together by weak vander Walls forces III : Silicon exists only in diamond structure due to its tendency to form p_(p)-p_(p) bonds to itself. In this :

Assertion : Carbon atom is tetravalent though it has two unpaired electrons. Reason : Carbon has unique ability to form p pi - p pi multiple bonds with itself like C = C, C -= C

Al has a smaller first ionization enthalpy than Mg. Consider the following statements : I. It is easier to remove 3p electron than 3s electron . II . 3p electron of Al is more shielded from the nucleus by the inner coreof electron than the 3s electrons of Mg III. 3s electron hasmore penetration power than 3p electron IV. Atomic radius of Al is more than Mg ( atomic number Al=13, Mg = 12 ) The correct statements are :

PASSAGE-I : Diamond and graphite are two allotropic forms of carbon which are crystalline in nature. They differ physically but chemically they are similar. Diamond is the hardest crystalline form of carbon. In diamond each carbon atom is linked to four other carbon atoms by covalent bonds. In graphite, each carbon atom is linked to three other carbon atoms by covalent bond. Graphite is relatively soft and greasy. It is a good conductor or electricity. Which of the folowing types of forces bind together the carbon atoms in diamond?
