Which compounds exhibit geometric isomerism? Draw and name the two isomers in each case:(b) 3-hexene
1 answer:
3-hexene shows geometrical isomers .
The geometrical isomers of 3-hexene are cis-3-hexene and trans-3-hexene.
Trans isomer has a higher melting point than cis isomer . the cis isomer has high boiling point . dipole moment is low in case of trans and high in case of cis .
<h3>What is isomerism ?</h3>it is a type of phenomena in which two or more compounds have same molecular or chemical formula but have different structure or spatial arrangement in 3D space .
<h3>Isomers :</h3>same molecular formula but different physical or chemical properties .
<h3>What is geometrical isomers ?</h3>it is a type of stereoisomers which have same molecular formula and same structure but different arrangement of atoms in space .

Answer : The concentration of a solution with an absorbance of 0.460 is, 0.177 M
Explanation :
Using Beer-Lambert's law :
where,
A = absorbance of solution
C = concentration of solution
l = path length
= molar absorptivity coefficient
From this we conclude that absorbance of solution is directly proportional to the concentration of solution at constant path length.
Thus, the relation between absorbance and concentration of solution will be:
Given:
= 0.350
= 0.460
= 0.135 M
= ?
Now put all the given values in the above formula, we get:
Therefore, the concentration of a solution with an absorbance of 0.460 is, 0.177 M
