Nano Chemistry

Nano stands for ------------------ meter

• 1 billionth

• 1 millionth

• 10000

• 1000

Nano meter is

• 10^ -6 meter

• 10^ -9 meter

• 10^ -3 meter

• 10^ -2 meter

The unique property of nano materials is its

• flexible structure

• malleable behaviour

• large surface area

• small surface area

An example of zero dimensional material is

• nano wires

• nano rods

• nano tubes

• quantum dots

Nano sized gold metal appears in ----------- colour

• green

• blue

• red

• yellow

Magic number is seen in

• nano tubes

• nano clusters

• nano rods

• nano wires

Molecular DNA is an example of

• nano wire

• nano rod

• nano cluster

• nano tube

When the gold metal is reduced in to nano size, its melting point ------------

• increases

• decreases

• remains constant

• no change

when one graphene sheet is rolled and its one end is closed, it gives

• nano wire

• nano rod

• single walled nano tube

• multi walled nano tube

When more number of graphene sheets are rolled and its one end is fused, it will give

• single walled nano tube

• nano tube

• multi walled nano tubes

• double walled nano tubes
