For the hydration of alkenes, the general chemical equation of the reaction is the following: RRC=CH 2 in H 2 O/acid → RRC(OH)-CH 3. A hydroxyl group (OH −) attaches to one carbon of the double bond, and a proton (H +) adds to the other carbon of the double bond. The reaction is highly exothermic.
During an acid-base reaction, an H+ is transferred from the acid to the base, but there is often little to observe—usually the reactants and products are both colorless solutions. This type of reaction produces heat, but just mixing a concentrated acid solution with water also tends to produce heat, so heat production is not a good way to ...

Electrophilic aromatic substitution is an organic reaction in which an atom that is attached to an aromatic system (usually hydrogen) is replaced by an electrophile.Some of the most important electrophilic aromatic substitutions are aromatic nitration, aromatic halogenation, aromatic sulfonation, and alkylation and acylation Friedel–Crafts reaction. ρ/T = 1.85 x 10-6. Here ρ is the density and T the tension in MKS units. For uniform stress, the ratio of arm radii at the base and the tip r 1 and r 2) is. log r 1 /r 2 = (ρ / 4T)v 2. where v is the escape velocity. For r 1 /r 2 less than 50, ρ/T must be less than 2.08 x 10-6.
