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 .

3. 4 g of a nonelectrolyte dissolved in 78. 3 g of water produces a solution that freezes at −4. 5∘c. what is the molar mass of
enyata [817]

3. 4 g of a nonelectrolyte dissolved in 78. 3 g of water produces a solution. The molar mass of the solute will be 17.94.

<h3>What is molar mass?</h3>

Molar mass of a substance is its mass in grams in per mole of  a solution.

Freezing point: Freezing point of a substance is a temperature at which a liquid starts to solidify.

Depression in the freezing point can be calculated

[Depression in freezing point of pure solvent—Freezing point of solution] =[(0) - (-4.5)] °C =4.5 °C

molar mass = Number of moles of solute m / Mass of solvent in Kg

3.4g / M x 1/ 0.0783 kg  = 43.42

Substitute AT by 4.5°C , Kr by 1.86 °C/m, and m by 43.42 m in equation (1) as follows:

1.86 x 43.42 / 4.5 = 17.94

Therefore, molar mass of solute to be 17.94.
