4. Alkene undergo Electrophilic Addition reactions since double bond of aljAlk acts as nucleophilie and try to add to Electrophile (HCl)
Hence Both H and Cl will add to double bond of Alkene.
5. Br2 addition is trans hence maleic acid forms trans dibromide.

14. An unknown with more than five carbon atoms is soluble in HCL, Which of the following is (are) likely to be? Amine ) Carboxylic acid C) Phenol D) Phenol or carboxylic acid 15. If an unknown is identified as either a carboxylic acid or phenol, the solubility in NalICO is used to differentiate between the two. This is done because: the carboxylic acid is a weaker acid than phenol and it will'not dissolve in NalHCO, the carboxylic acid is...

Predict the product for each of the following reactions:
Hint/ Explanation:
- For the first reaction, HCl will add
to the carbon atoms of the triple bond. The addition is
stereoselective. A similar addition occurs with the resulting
compound and HBr. Consider Markovnikov\'s rule for determining the
regiochemistry.
- Internal alkynes undergo
stereoselective hydrohalogenation via anti addition to give the (Z)
product.

Identify each of the following reactions as synthesis, decomposition, combustion, single replacement, or double replacement. If the reaction is a single or double replacement reaction, tell if the reaction occurs spontaneously. If the reaction does not occur spontaneously, write "No Reaction." If the reaction does occur spontaneously for single and double replacement write a balanced molecular, total ionic, and net ionic equation. For the other types of reactions, write a balanced chemical equation. 2. Water and dinitrogen trioxide gas 3....
