Can a group of people function effectively without someone being in charge? I believe that a group of people cannot function effectively without someone being in charge. There are 2 main points. A leader is someone who gathers the group together‚ and allows the group work more efficiently. I believe that a group leader is supposed to be a role model for the whole group‚ someone that everyone follows. If a group didn’t have a leader‚ the group would be scattered. Firstly‚ a leader is responsible

CARBON AND ITS COMPOUNDS Covalent Bond: A chemical bond formed by the sharing of two atoms. Types of Covalent Bonds i. Single Covalent Bond: A type of bond formed by sharing of one pair of electrons between two atoms. ii. Double Covalent Bond: A type of bond formed by sharing of two pairs of electrons between two atoms. iii. Triple Covalent Bond: A type of bond formed by sharing of three pairs of electrons between two atoms. Properties of Covalent Bond i. Their B.P. and M.P

These reactions tend to split into two groups: Addition of the Grignard reagent to a compound containing multiple bond group such as: Which is the process of addition of the R group of RMgX occurs at the less electronegative and the MgX group at the higher electronegative atom. Which means that the R group is the negative and the MgX group is the positive ends of the dipole in the

that it stayed closer to the stationary phase. Caffeine contains four amine groups that are extremely polar as a result of the hydrogen bond and amide functional group. Acetaminophen was found to be the second most polar analgesic drug tested. Acetaminophen contains a polar alcohol group on one side and amide group on the other but also includes non-polar functional groups that consisted of the benzene ring and methyl group. Acetylsalicylic acid low polarity results from only containing a carboxylic

hydroxyl group of an alcohol. This type of reaction is representative of an important class of reactions in organic chemistry called nucleophilic aliphatic substitution reactions. There are numerous ways of doing this transformation‚ and we will discuss these in lecture. In this experiment you will convert an alcohol to an alkyl halide by reaction with a hydrohalic acid. The overall reaction is shown in equation 1; however the mechanism of the reaction depends on the structure of the alkyl group bearing

Abstract Introduction The acylation of the α carbon position of a carbonyl group is one of the greatest breakthroughs that has benefited chemists in organic synthesis particularly when in need of building a carbon skeleton of interest in a molecule. For one to be able perform this acylation technique‚ there are two mar approaches which are employable. The first method involves the deprotonation of the α-Carbon atom which has a pKa known to be ̴20 through the use of a strong base for instance

Isomers are molecules that a) react readily with one another b) have the same molecular formula c) have different molecular masses d) differ in the number of unsaturated bonds e) must contain the same functional group 3. In living organisms‚ buffers do which of the following? a) prevent charged particles from entering cells b) neutralize the effect of enzymes c) maintain pH in the cells within a narrow range‚ allowing enzymes to function d) allow
