Hydrolysis of a compound B(formula C2H6Cl12) was carried out by refluxing with excess potassium hydroxide solution.The resulting solution was acidified with dilute nitric acid and excess silver nitrate added to precipitate the chloride ions as silver chloride,0.718g of silver chloride was formed from 0.805g of B. (a)calculate the number of chlorine atoms present in each molecule of B which are liberated by hydrolysis. (b)suggest an explanation for the result obtained in (a). (c)give a possible structure
R is a liquid which reacts virgorously with concentrated aqueous ammonia to form a solid which is readily dehydrated by warming with phosphorus v oxide. Write equations for the reactions involved
calculate the mass of potassium hydrogen phthalate (KHP) needed to prepare a 0.1 M solution in a 250.0ml volumetric flask given that the molar mass of potassium hydrogen phthalate is 204.23 g/mol.
What stereochemisyry would you expect for the alkene obtained by E2 elimination of(1R,2R-1,2-dibromo--1,2-diphenylethane?Draw the Newman structure.
2.Draw the resonance structures for the products of all nitrogen in a compound below and determine which will protonate first(6marks)
H2N-C=NH-NH-CH3
3.How do I identify the most acidic proton in molecules using electronic factors to explain their stabilization conjugated bases?
More especially in molecules having a Carbon bonded to a carbon and 2 Oxygens??
4.From the reaction below,only one product will form.Propose a mechanism and use your knowledge of intermediate stability to predict the structure of the expected product.
Reaction:

Please explain what is the chemical reactions and its principles and also explain why the diluted juice (water + calamansi (it is a citrus fruit here in the Philippines, it's like a lime but circle in shape and smaller) changed in color (from pale yellow it turns into dark orange) when the supernatant (water + steel scrubber (The liquid turns into darker shade due to rust) was mixed with the diluted juice. Thank you so much, can you please also put references since it is necessary for our activity.
