The way in which four stereoisomers arise for 3-penten-2-ol has to be explained. Concept Introduction: Alkene: Unsaturated hydrocarbons having at least one double bond between two carbon atoms are known as alkenes . Geometric isomers: Two compounds are considered as geometric isomers of each other if both contain same number of atoms but different in their arrangement. E configuration: The geometric isomers are given E configuration if high priority groups are placed on opposite sides of the double bond. Z configuration: The geometric isomers are given Z configuration if high priority groups are placed on same sides of the double bond. Chirality: It refers to a Carbon atom in a molecule that contains four different substituents. According to Cahn-Ingold-Prelog system, The group attached to asymmetric center should be ranked based on the atomic number of atom which directly connected to asymmetric center. The higher the atomic number of atom, higher the priority. If there is tie, then consider the next atoms attached to the connected atom and so on. Check the direction of arrow drawn in the direction of decreasing priority. If the arrow points clockwise direction, then the atom has R configuration. If the arrow points counterclockwise direction, then the atom has S configuration. If the group with lowest priority is not bonded by a hatched wedge, then interchange this group (lowest priority) by group bonded to hatched wedge and draw the arrow in priority order but the configuration is assigned as just reverse.

Answer 1

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .

An open vessel containing water stands in a laboratory measuring 5.0 m x 5.0 m x 3.0 m at 25 °C ; the vapor pressure (vp) of water at this temperature is 3.2 kPa. When the system has come to equilibrium, what mass of water will be found in the air if there is no ventilation? Repeat the calculation for open vessels containing benzene (vp = 13.1 kPa) and mercury (vp = 0.23 Pa)

Every chemist knows to ‘add acid to water with constant stirring’ when diluting a concentrated acid in order to keep the solution from spewing boiling acid all over the place. Explain how this one fact is enough to prove that strong acids and water do not form ideal solutions.
