3-Methylpent-2-ene (CH3CH=C(CH3)CH2CH3) reacts with Hydrogen Chloride(HCl) forming a major and minor product. Please name the reaction, draw the mechanism for the formation of the major product and briefly explain why there is a major and a minor product.

This is an example of electrophilic addition.(It's easier to explain with the mechanism drawn) The mechanism proceeds by electrophilic attack of the Hydrogen in HCl originating from the double bond in 3-m...

Consider the transition metal complex [CoCl3(CO)3]. What is a) The oxidation state of the metal centre. b) The dn configuration of the metal centre. c) The co-ordination number of the metal centre.

a) +3. Cl ligands carry a negative charge while CO ligands are neutral so the all together the ligands have a charge of -3. Since the complex is neutral overall, the metal must cancel out the charge of t...

Ethanol can be made from the reaction between ethene and water. The reaction is exothermic and occurs at a high temperature. Describe and explain the effect of raising the temperature on the rate of achievement of equilibrium and the equilibrium yield.

The rate of achievement of equilibrium increases. This can be explained by collision theory. Because the temperature is increases the reactants have more energy and therefor the collisions between them be...
