Answer: alcohols
Explanation:
The carbonyl group refers to C=O. It is contained in aldehyde, Ketones, carboxylic acids , esters, amides and acyl chlorides. They are not found in alcohols. The alchols are generally ROH. They do not contain any carbon-oxygen unsaturated bond in their structure hence the answer.
Answer: His and Lys are deprotonated but Asp will be protonated.
Explanation:
As the pH is given as 7.4 and pK of His is given as 6.00. There will occur a positive charge on His when it's pH < pK therefore, it is neutral at the given pH.
As the pK value of Lys is 10.53 that is greater than the pH of 7.40. Therefore, charge on Lys is positive.
As the pK value of Asp is 3.65 which is less than the pH value of 7.40. Hence, Asp has a negative charge.
Therefore, we can conclude that His and Lys are deprotonated but Asp will be protonated.
The atoms C,H,O and N becomes more electronegative as the periodic table's right side and top get increasingly electronegative as you move down it. A hydrogen bond needs to share elements with hydrogen in order to exist.
As you move up and to the right of the periodic table, the electronegative properties increase. To form a hydrogen bond, elements would have to be shared with hydrogen. Each element becomes increasingly electronegative as you move further right on the periodic table, with the exception of noble gases (which aren't particularly reactive).
In order to obtain stability, atoms C, H, O, and N would therefore most likely desire to share their electrons (i.e., they are more electronegative because they wish to "hog" electrons). Due to its intermediate electronegativity, hydrogen has a mid-range potential for forming bonds with other molecules.
