Interpretation Introduction

Interpretation:

Vapour pressure is pressure exerted by vapour when its pure condensed phase condensed phase (solid orliquoid) is in equilibrium with gas phase (Vapour) vapour pressure is function temper ature for a given pure form vapour pressure of a substance is instrisic property. There are there 1.0L flasks, maintained at 308Kare connected to each other with stop cocks, initially, the stop cock s are closed, there three are opened and missed you have to find out final pressure of mixture. Initially each flaks are maintained at temperature 308K.

In the first flask N₂ is kept at 1 atom.

In the second flask 2.0g of H₂O His kept and in third flask 0.50g of ethanol is kept.

It is given that the vapour pressure of H₂O at 308K is 4233Hg and that of ethanol is 102mmHg.

Concept introduction:

Total pressure inside the flask is summation of pressure due to each component

P_{total> =P_N₂+P_H₂O}+P_C₂H₆o

Ideal gas equation

Pv=nRT

These are synthesis questions. You need to show how the starting material can be converted into the product(s) shown. You may use any reactions we have learned. Show all the reagents you need. Show each molecule synthesized along the way and be sure to pay attention to the regiochemistry and stereochemistry preferences for each reaction. If a racemic molecule is made along the way, you need to draw both enantiomers and label the mixture as "racemic". All of the carbon atoms of the products must come from the starting material! ? H H

Q5: Draw every stereoisomer for 1-bromo-2-chloro-1,2-difluorocyclopentane. Clearly show stereochemistry by drawing the wedge-and-dashed bonds. Describe the relationship between each pair of the stereoisomers you have drawn.

Classify each pair of molecules according to whether or not they can participate in hydrogen bonding with one another. Participate in hydrogen bonding CH3COCH3 and CH3COCH2CH3 H2O and (CH3CH2)2CO CH3COCH3 and CH₂ CHO Answer Bank Do not participate in hydrogen bonding CH3CH2OH and HCHO CH3COCH2CH3 and CH3OH
