Question

Curved arrows represent electron movements. Chemists utilize curved-arrow (electron-pushing) notation as a bookkeeping tool to keep track of electron movements- bond breaking and formation- within and between compounds. Such understanding aids the chemist in mentally digesting complex reactions, predicting products for an unfamiliar reaction (e.g., on arn exam), or even how to exploit a reaction for industrial or medicinal benefits (e.g., selectiveadiolabeling) Curved arrows in Sapling Learning must start on an electron source, either a nonbonding electron or bond and point towards an atom or bond. Identify the correct results for the four scenarios below 1. If an arrow starts with a lone pain 2. If an arrow starts on a bond, the bond order both electrons will be donated to the adjacent atom. a pi bond must be formed the lone pair will turn into a O will remain the same will increase by 1 will decrease by1 O O bond 3. If an arrow starts from a bond and points towards an adjacent atom, the atom 4. If an arrow points towards a bond, the bond er O will gain one additional lone pair will have the same number of lone pairs will lose one lone pair will increase by 1 will decrease by 1 will remain the same O O

Explanation / Answer

1) If the arrow starts with a lone pair , THE LONE PAIR WILL TURN INTO A BOND

2)If the arrow starts on a bond, the bond order will DECREASE BY 1.

3) If the arrow starts from a bod and points towards ajacent atom, the atom WILL GAIN ONE ADDITIONAL LONE PAIR.

4) If an arrow opoints towards a bond, the order will increase by 1.
