A. draw the structure of the tetrahedral intermediate initially formed in the reaction shown. you do not have to consider stereo
julsineya [31]
The reaction is shown below, Acid protonates the carbonyl oxygen and makes the carbonyl carbon more electrophilic. Water attacks on activated carbonyl group and forms a tetrahedral intermediate.

Intermediate:
                    Structure of Intermediate is shown both in 2-D and 3-D (below attached). 

Carbonyl group is regenerated with the elimination of ethanol.

Reaction is as below, The final product is carboxylic acid.

How many different isomers can be derived from ethylene if two hydrogen atoms are replaced by a fl uorine atom and a chlorine at
svp [43]
Answer:
             THREE<span> different isomers can be derived from ethylene if two hydrogen atoms are replaced by a fl uorine atom and a chlorine atom.

Explanation:
                   When two Hydrogen atoms in ethylene (C</span>₂H₄) are replaced with Fluorine and Chlorine atom then the new molecular formula is C₂H₂FCl.
                    Compounds having same Molecular formula but different structural formula are called as Isomers.
                     First Isomer of C₂H₂FCl is 1-chloro-1-fluoroethene, in which F and Cl at geminal position (attached to same Carbon atom).
                     Other two Isomers are Geometrical Isomers of 1-chloro-2-fluoroethene, in which F and Cl at different carbon atom and having different position is space. The one in which both F and Cl at opposite side forms (<em>trans</em>)-1-chloro-2-fluoroethene and the one in which both are in same side is called as (<em>cis</em>)-1-chloro-2-fluoroethene.

1,4-Pentadiene has a AHhydro = -254 kJ/mol while trans-1,3-pentadiene has a AHhydra = -226 kJ/mol. Explain this difference in he
julsineya [31]

Answer:

trans-1,3-pentadiene is more stable than 1,4-pentadiene due to presence of a conjugated double bond.

Explanation:

Here, \Delta H_{hydro}=H(hydrogenated pdt.)-H(diene)

H(hydrogenated pdt.) is same for both 1,4-pentadiene and 1,3-pentadiene as they both produce pentane after hydrogenation

H(diene) depends on stability of diene.

More stable a diene, lesser will be it's H(diene) value (more neagtive).

trans-1,3-pentadiene is more stable than 1,4-pentadiene due to presence of a conjugated double bond.

Hence, \Delta H_{hydro} is higher (less negative) for trans-1,3-pentadiene
