Amino acids behave like salts rather tha...

Amino acids behave like salts rather than simple amines or carboxylic acids. This behavior is due to the presence of both acidic (COOH) and basic `(-NH_(2))` group in the same molecule. In aqueous solution, the carboxyl group can lose a proton and amino group can accept a proton, giving rise to a dipolar lon known as Zwitter ion.
Zwitter ion exists.

A

at pH = 7

B

in acidic medium

C

in basic medium

D

at a specific pH

Amino acids behave like salts rather than simple amines or carboxylic acids. Explain.

Explain the following : (i) Amino acids behave like salts rather than simple amines or carboxylic acids. (ii) The two strands of DNA are complementary to each other.

Assertion : Alpha (alpha)- amino acids exist as internal salt in solution as they have amino and carboxylic acid groups in near vicinity. Reason :H^(+) ion given by carboyxylic group (-COOH) is captured by amino group (-NH_(2)) having lone pair of electrons.

Refer to the given graph showing state of ionisation of zwitterion. Select the correct statements regarding zwitterion. (i) Zwitterions can be formed from compunds that contain both acid groups and basic groups in their molecules. (ii) A zwitterion can act either as proton donor or proton acceptor. (iii) A monoamine monocarboxylic alpha -amino acid is a acid at high pH as both the groups (amino and carboxyl) lose a proton. (iv) Amino acids in solution at neutral pH exist predominantly as dipolar ions, the amino group is protonated (-NH_(3)^(+)) and the carboxyl group is deprotonated (-COO^(-)) .

The origin of acidity and basicity in organic compound is great interest and provides an extensive comparison. Among hydrocarbons % a character is taken in aC Count while to decide the acidity, in simple aliphatic acids, more the number of alkyl groups, (+1 effect) less is the acidity & more the (-1 effect) groups larger the acidity and vice-versa in the case of simple alphatic bases. Benzoic acid is more stronger than carboxylic acid as benzoate ion is stablised more by resonance. Aromatic amines are less basic than apiphatic amine as the electron pair is less available in case of aromatic amines. The presence of solvent also plays a very important role and at time governs the order too. Amongst the following the most basic compound is -

Carboxylic acids containing an amino group (-NH_(2)) as a substituent are called amino acids. When this amino group substitution is at alpha position with respect to carboxylic group, the aminoacid is called alpha -amino acid. The aminoacids with two carboxylic acids are called acidic amino acids whereas aminoacids with two amino group are called basic amino acids Amino acids show amphoteric character. Ali chiral natural amino acids exist in L-form. : What would be the net charge on the given amino acid at pH=14?
