c) For each of the compounds i) to iii) below, identify and draw as many structural isomers as you can, explaining the type of structural isomerism in each case. For each structural isomer you draw, explain whether it exhibits stereoisomerism, stating the type of stereoisomerism where applicable and drawing diagrams of the stereoisomeric pairs. i) Br₂C=CH₂ ii) CH3CH2CH2CHO iii) CH3(CH2) 3CH2Cl

DRAW THE FOLLOWING

Please don't provide handwriting solution

Please check if information below about alcohols and ethers in organic chemistry are correct  please I am really having troubl   ALCOHOLS AND ETHERS   INTRODUCTION:   Alcohols:  Organic compounds with (-OH) groups attached to a carbon atom Used as solvents, fuels, and in the production of chemicals/pharmaceuticals Have biological roles and are found in alcoholic beverages Alcohols have a characteristic -OH group, which gives them a polar nature and makes them soluble in water and other polar solvents. They have higher boiling points compared to similar-sized hydrocarbons due to the hydrogen bonding between the -OH groups. Alcohols can undergo oxidation reactions to form aldehydes, ketones, and carboxylic acids. They can also undergo dehydration reactions to form alkenes and water.   Ethers:  Organic compounds with an oxygen atom bonded to two carbon atoms Ethers have a relatively non-polar nature due to the lack of a polar -OH group. As a result, they have low solubility in water…
