Give the letter for the side group that would interact with cations the best.

3. Explain how LDPE and LLDPE differ in terms of structure, synthesis and properties.

A student was attempting to prepare chiral amine with the structure shown below. After numerous attempts, each sample turned out to be optically inactive. Briefly explain why the synthesis was unsuccessful. N..

The photo dimerization of benzophenone to benzopinacol is initiated by what type of electronic transition that then rapidly decomposes to a diradical since putting in electrons in anti bonds breaks bonds! The diradical then starts abstracting hydrogens from solution as pictured in the text? σ = electrons in sigma bonds n = electrons in non-bonding orbitals π electrons in pi bonds. anti bonds Hint: This process is very important because although the molecule responsible for human vision (retinal) is not a very long conjugated pi system, this transition allows retinal to absorb visible light. a. n to σ* b. σ to σ* C. π το π d. n to П e. σ to П* f. π to σ'

Give the curved arrow for the structure and predict the product H*

O Use the polygon rule to draw the MO energy diagram of the cyclononatetraenyl anion. Assuming planarity, would this ion be aromatic or antiaromatic?

2.How much excess acid uwos used to make the 'nitrous with the primary amine! and acid"“ HOND that will make the diazo salt

The unusual molecule below is aromatic and somewhat stable in spite of the positive charge on oxygen. Draw all possible resonance structures to show how the electrons can move about the ring in an uninterrupted circuit.
