3. Draw the chemical mechanism (with electron-pushing arrows) for the first step of RNA splicing (as catalyzed by the splicosome). Be sure to explicitly show the attacking nucleophile, the phosphate at the intron-exon junction, the intron branch point and the leaving group in the reaction.

Draw a reasonable, step by step arrow pushing mechanism for
the overall reaction. You may abbreviate non-involved parts of any
of the molecules with 'R' groups, and you can assume that water is
present in the reaction (to act as either an acid or a base).

QUESTION: Draw an arrow-pushing mechanism for the FIRST STEP of
this synthetic sequence.
In this laboratory experiment, you will synthesize a RTIL, 1-hexyl-3-methylimidazolium hexafluorophosphate, using a two-step process involving nucleophilic substitution and anion exchange. 1-Hexyl-3-methylimidazolium hexafluorophosphate and its structural analogs have long names. Therefore, they are often abbreviated as [Cn-mim X, where n = the number of carbons in the alkyl chain of the cation, ‘mim' stands for methylimidazolium and X = the anion. P -N N N-methylimidazole - NON...
