What mass of sodium hydroxide can be made by reacting 2.3 grams of sodium with water

 Including possible stereochemistry, draw and name all possible alkynes with a formula of C₇H₁₂.

1.  Draw the products of the following alkene reactions:

a. 2-methylhex-2-ene in an oxymercuration - demercuration reaction

b.(E)-3-methylhex-3-ene in an osmium tetroxide hydroxylation reaction

c. 2-methylhex-1-ene in a KMnO4 oxidative cleavage reaction

d. (E)-3-methylhex-2-ene + bromine

e. 5-methylhex-1-ene in an epoxidation / hydroxylation reaction

A sample containing approximately 1gram of an organic solute dissolve in 100ml of water the aqueous solution is then shaken with 100ml of ether analysis of ether show that 0.7g of y is extracted

1. What is the distribution coefficient of this system

2 what fraction of y will have been extracted by 425ml portion of the ether

Multi step synthesis of ethyl ethanoate from ethanal? So including reagents end products, conditions aswell. Thankss

Choosing an example, explain how it reacts, mechanism, balanced equation, the IUPAC name of organic reactants and products for 

Halogenalkanes: nucleophillic substitution forming alcohols nitriles, amines, and elimination forming Alkene -thanks

Compare the mechanisms for the following substitution and addition reactions of benzene:

o the Friedel-Crafts reaction 

o the sulfonation of benzene

o the chlorination of benzene 

o the hydrogenation benzene

You will need to illustrate and explain the reaction mechanism for each one, as well as the similarities and differences that exist between them

• Explain the chemical properties of benzene, phenol and methylbenzene in terms of the reactions they undergo. You will need to give their key chemical reactions and explain why these are suitable and important in specific industrial reactions.

• Explain the accepted structure of benzene in terms of hybridisation, sigma and pi bonding, and delocalisation of electrons. Include examples of evidence (such as infrared, x-ray and thermochemical analysis) that support the structure of benzene as being very stable and regularly shaped. Include within your explanation why this evidence also disproves the originally suggested Kekulé structure for benzene, including reference to the bond lengths of C-C, C=C and those within benzene

1.  Draw the products of the following alkene reactions:

a. (E)-2-methylhex-3-ene + ozone, then Zn in acidic (H3O⁺) medium

b. 3-methylhex-1-ene + HBr in ether

c. (Z)-3-methylhex-3-ene + H2 with platinum catalyst

d. (R)-4-methylhex-1-ene in a hydroboration reaction

e. (Z)-3-methylhex-2-ene + KI in phosphoric acid
