Label or circle CARBON chirality centers for both structures below and determine the maximum number of stereoisometric forms: cortisone (steroid used for anti-allergen creams) .OH HO # of Stereoisomers Possible: HO histidine (one of the 20 amino acids) HO NH₂ # of Stereoisomers Possible:

Hw 1.

Please send me the question in 20 minutes it's very urgent plz

Consider this molecule, which contains one chirality center. What is the highest-priority substituent at this chirality center? () -CH,CH, -CH, -Br What is the lowest-priority substituent at this chirality center? -CH, -CH₂CH₂ Name the structure. (S)-2-bromobutane (R)-2-bromobutane 0 FOREX OH zoom in Br Q

Can you please explain how to go about assigning chirality priority from 1-4?

What is the stereochemical relationship between the compounds below? OH HO HOʻ H OH Но- Но H- H3C- H3C- -OH Но CH3 ČH3 CH3 ČH3 I II III O l and III are identical and are diastereomers of II O Il and IIII are enantiomers and are diastereomers of I O Il and III are identical, and are enantiomers of I O l and Il are enantiomers, and are diastereomers of II O l and Il are enantiomers and III is a meso compound
