Premium Aldehyde Alcohol Functional group
molecules become covalently bonded to each other with the removal of a water molecule. - When a bond forms between two monomers each monomer contributes part of the water molecule that is released during the reaction - On monomer provides a hydroxyl group (-OH)‚ while the other provides a hydrogen (-H). This reaction is

are the primary‚ secondary and the tertiary alcohols‚ aldehydes and ketones? Alcohols are compounds in which one or more hydrogen atoms in an alkane have been replaced by an -OH group. Note however that there are different kinds of alcohols and Alcohols are categorized into different classes depending on how the -OH group is
Premium Alcohol Aldehyde Functional group
alcohol which contains a hydroxyl group (OH-) has a partial negative charge compared to the alkyl group bound to it which is Isopropyl in this lab. The reason is that oxygen has higher electronegativity compared to carbon. So‚ there is more attraction to the lone pair electrons around oxygen which makes the hydroxyl group partially negative. Analyzing the structure of the glacial acetic acid‚ we notice that the hydroxyl group and the oxygen on the carbonyl group will draw electrons towards themselves
Premium Acetic acid Carboxylic acid Ester
Physical properties of organic compound Low boiling point group: alkane‚ alkene‚ alkyne and ether Boiling point is the exact temperature that the state of compound change from liquid to gas‚ which need to break the intermolecular forces. The stronger the intermolecular forces‚ the higher the boiling point. Since straight chain alkane‚ alkene and alkyne only experience dispersion forces‚ the compound with more carbons have higher boiling point as more carbons contribute more forces. Branched

Premium Sulfuric acid Chemistry Functional group
thionyl chloride as a nucleophile1. Thionyl chloride then undergoes a loss of a leaving group as chlorine will leave1. The compound is then deprotonated from the free chlorine and SO2 is expelled as a gas as it is an excellent leaving group (Figure 2)1. Diethyl amine can then be reacted with the compound via a nucleophilic attack. Once the amine is attached chlorine will leave as a leaving group as the carbonyl group reforms (Figure 3)1. This provides a simple two-step process to attach a diethyl amine
