IR spectroscopy

When 2-bromopropane reacts with ethoxide ion, two products are formed; one is the product of Sn2 substitution and the other is the product of E2 elimination. What is the the structures of both products and how can you distinguished them using IR spectroscopy? Thanks.

Structure

What is the structures for 2-methyl-1,3-butadiene and (2Z, 4Z)-hexadiene?

Mass spectroscopy

For the attached compound, I need help in determining the value of m/z for the molecular ion (parent peak) and the likely value for m/x for the beak peak? What is the molecular ion: m/z? and Base peak: m/z? Thanks.

mass spectrum

For the spectrum attached in document, I need help with calculating a possible molecular formual for this compound. This compound contains C, H, and Br. Can you also show your work, I want to check my work. Thanks.

Spectrum

For the two compounds in the document, how many signals you would expect the molecule to have in both the 13C NMR spectra and in the proton NMR specturm. Can you briefly explain to me, I haven't a hard time understand this. Thanks.

13C NMR spectral data

I need help with matching the spectral data to the correct structures. Please see attachment.

Splitting patterns

I need help predicting the splitting patterns that you would expect for each proton (proton 1 and proton2) in 2,3-dimethylbutane. What is the number of adjacent hydrogens and what is the splitting patterns.

Mechanism

Consider the reaction in attached document. What is a stepwise mechanism that accounts for both of the products shown. Please show me the mechanism. Show all intermediate structures and all electron flow with arrows. Also include resonance. In addition, what is the non-prefeered products of electrophilic addition to the opposit ...continues

Addition of bromine to 2-pentene

Write structure of dibromine products that you think will be formed as a result of the reaction of Z-2-Pentene with Bromine.How about the dibromide products predicted when E-2-Pentene reacts with Bromine.
