Q

C-C bond length is the maximum in which allotrope

A

diamond

20
Q

Fullerenes have smooth/rough structure

A

smooth

21
Q

how are fullerne formed

A

fullerenes are made by the heating of graphite in an electric arc in presents of inert gases such as helium or argon

22
Q

hydrocarbons with water forms ? and at which condition

A

it makes CO + H2 and at very high temperature

23
Q

Producer gas equation

A

prodcuer gas= CO + N2

24
Q

Why are CO poisonous

A

CO is highly poisnous as it is about 300 more stable with a complex with haemoglobin as compared to oxyden heamoglobin complex this prevents RBC to carry oxygen and hence results intro death

25
Q

Dry ice is formed by

A

dry ice is mafe by allowing thr liquifies CO2 to expand rapidly

26
Q

Quartz is used in

A

quartz is extensively used as a piezoelectric material, it has possible to possible develop extremely accurate clocks modern radio and television broadcasting and mobile radio comms

27
Q

SiO4^-4 structre and shape

A

shape= tetrahedral

28
Q

SiO number of bonded/unbonded O formulae/trick’

A
29
Q

Si Polymerization

A
30
Q

Glasses Is made of up

A

silicates

31
Q

Silicone dielectric constant , thermal stability, resistance to oxidation

A

high dielectric strength and thermal stability and resistance to oxidation and chemicals

32
Q

Eg of silicate

A

zeolites

33
Q

why does grpahite conduccts electricity

A

becuase it has an unpaired electron

34
Q

Does PbI4 exists? why so?

A

no it doesnt exists as it doesnt release enough energy to unpair 6s2 electrons

35
Q

which chloride of grp 14 doesn’t hydrolyses by water

A

CCl4 cuz it doesn’t has D orbitals to accompany hh2O

36
Q

Carbon with steam forms ____ and it is also called?

A

carbon mono oxide and it is also called water gas or synthesis gas

37
Q

CO2 with water forms

A

H2CO3

38
Q

SnCl2 with Cl- forms?

A
39
Q

SnCl2 with CuCl2 forms?

A
40
Q

SnCl2 with NMe3 forms?

ans what is the type of bond formed?

A

coordinate bond is formed

41
Q
A

for linear polymer! we must form bonds with only 2 sides! and for termination just one side

therefore the one with Cl will form the linear polymer and the one will one Cl will terminate the chain

42
Q

What’s used as a drying agent?

A

silica gel can be used as a drying agent

43
Q

what is used as a sealant?!

A

silicone

44
Q

what is used as an ion exchanger?

A

zeolites(silicate)

45
Q

fusing of 5 and 6 membered rings in fullerene

A

the 6 membered rings are fused to both six and five-membered rings

the 5 membered rings are fused only to 6 membered rings
