Amount of heat whether absorbed or released is to be calculated when given amount work is done by the system on surrounding. Concept introduction: The first law of thermodynamics states that heat is a form of energy. Energy can neither be created nor be destroyed in an isolated system. Equation for the first law is as follows: Δ U = q + w Here, U is the internal energy of the system, q is the heat given to or removed from the system, and w is the work done by or to the system. If the sign of q is positive, heat is absorbed by the system. If the sign of q is negative, heat is released by the system.

Interpretation Introduction

Interpretation:

Amount of heat whether absorbed or released is to be calculated when given amount work is done by the system on surrounding.

Concept introduction:

The first law of thermodynamics states that heat is a form of energy. Energy can neither be created nor be destroyed in an isolated system.

Equation for the first law is as follows:

ΔU=q+w

Here, U is the internal energy of the system, q is the heat given to or removed from the system, and w is the work done by or to the system.

If the sign of q is positive, heat is absorbed by the system.

If the sign of q is negative, heat is released by the system.

Be sure to include any relevant stereochemistry in the product structure. + SK F Br + (b) In which solvent would this reaction proceed the fastest (Circle one) Methanol Acetone (c) Imagine that you are working for a chemical company and it was your job to perform a similar reaction to the one above, with the exception of the S atom in this reaction being replaced by an O atom. During the reaction, you observe the formation of three separate molecules instead of the single molecule obtained above. What is the likeliest other products that are formed? Draw them in the box provided.

3. For the reactions below, draw the arrows corresponding to the transformations and draw in the boxes the reactants or products as indicated. Note: Part A should have arrows drawn going from the reactants to the middle structure and the arrows on the middle structure that would yield the final structure. For part B, you will need to draw in the reactant before being able to draw the arrows corresponding to product formation. A. B. Rearrangement ΘΗ

2. Draw the arrows required to make the following reactions occur. Please ensure your arrows point from exactly where you want to exactly where you want. If it is unclear from where arrows start or where they end, only partial credit will be given. Note: You may need to draw in lone pairs before drawing the arrows. A. B. H-Br 人 C Θ CI H Cl Θ + Br O
