The reaction between C2H6 and
Cl2 by addition is C2H4Cl2 or dichloroethane. It must be under the presence of
sunlight because halogen such as chlorine cannot easily react with the sigma
bond of alkane such as ethane.
The color of corn is different than the color of gasoline or coal.
Explanation:
At each reflecting surface (benzene and glass) there will be 180 degree phase change.
Now, for constructive interference the optical path in benzene is
.
Formula to calculate thickness of a benzene thin film is as follows.
Optical path length through benzene (
) = 
Hence, substituting the given values into the above formula as follows.
Optical path length through benzene = 
d = 
=
=
(as 1 nm = 
= 204.9 m
Thus, we can conclude that minimum thickness of benzene is 204.9 m.
