Attached below diagram of the eight diastereomers
The Isomer that reacts so slowly is DIASTEREOMER 8
Explanation:
The Isomer that reacts so slowly is DIASTEREOMER 8 in an E2 reaction and this is because no pair of chlorine and hydrogen atoms can assume the anti-periplanar orientation that is preferred in an E2 elimination

<u>Answer:</u> The freezing point of solution is -5.11°C
<u>Explanation:</u>
Vant hoff factor for ionic solute is the number of ions that are present in a solution. The equation for the ionization of sodium chloride follows:
The total number of ions present in the solution are 2.
To calculate the molality of solution, we use the equation:
Where,
= Given mass of solute (NaCl) = 7.57 g
= Molar mass of solute (NaCl) = 58.44 g/mol
= Mass of solvent (liquid X) = 350.0 g
Putting values in above equation, we get:
To calculate the depression in freezing point, we use the equation:
where,
i = Vant hoff factor = 2
= molal freezing point depression constant = 6.90°C/m
m = molality of solution = 0.370 m
Putting values in above equation, we get:
Depression in freezing point is defined as the difference in the freezing point of water and freezing point of solution.
= 5.11 °C
Freezing point of water = 0°C
Freezing point of solution = ?
Putting values in above equation, we get:
Hence, the freezing point of solution is -5.11°C
Answer:
Density,
Explanation:
Given that,
Mass of marble slab is 38.6 kg or 38600 g
The dimensions of the slab is 23 cm × 17 cm ×4 cm
We know that the density of an object is given in terms of its mass volume as follows :
So, the density of the marble slab is
