I think the correct answer would be B. The process of electroplating uses a direct current in order to give a cheap metal the apperance and resistance of a more expensive metal by coating it with a certain metal. The current reduces the dissolved metal ions to form a thin coating on a surface.
Alkenes undergo
Electrophillic Addition Reactions. Electrophiles are added across double bond. In given reaction the
H⁺ is first added across double bond as the double bond being denser in electron density act as a neucleophile. A
carbocation formed depends upon the nature of Alkene, if alkene is
symmetrical (as in our case) then positive charge can get any position, but in case of
unsymmetrical alkene the positive charge will go to that carbon which is attached to more carbon atoms. Then the water molecule attacks the carbocation and forms
alcohol.
Answer:
c^21, t^729, CH^56>748, do this to calculate the moceluar mass
Answer:Strong bases: OH-, CH3O-, CN-
Nucleophiles: OH-,CN-, NH2-
Leaving groups: Br-, Cl-, H2O,NH3
Explanation: Strong bases have a greater ability to abstract a proton in an elimination reaction. For instance, the OH- easily abstracts a proton to form water. Nucleophilicity is a kinetic property. It measures the rate at which a specie displaces a leaving group from an alkyl halide Good leaving groups are stable anions or neutral molecules. They are often conjugate bases of strong acids.
The hydroxide ion rarely, or almost never acts as a leaving group in SN2 reactions
