Question

Which of the following molecules contain a stereocentre? Br e go alonna 1 2 3 Select one: O a. 2 and 3 only O b. None of the molecules O c. All of the molecules O d. 1 and 3 only O e. 4 only Which is the correct electron configuration for an isolated Ni2+ ion? Select one: O a. [Ar]3d8 O b. [Ar]3d745 O c. [Ar]3d7 O d. [Ar]3d6452 O e. [Ar]3d5452

Answer 1

→ 2 figurce 2 hence option (33 and 3 have stereo centeres as is covereect. sepsesented in (at) (a a and 3 only. → Ni = [Ao lig 4S² 328 Ni 3t = [folio 3d7 Electson semove fisst the ouere shell from the as subshell as of is CamScanner

If the same priority groups are in same direction of the double bond then it is called "Z" configuration.

If the same priority groups are in opposite direction of the double bond then it is called "E" configuration.

* Vio I Boe live m mode priority group (Accooding to Atomic numbere) are on the same side then they are in a forem stade of oxidation w i and iv only [vcensCha] couredincation Numbere = 6 oxidation state ato-4=+ att4 22: +3 CS Scalopdimulach is correct.
