Empirical formulafor ferrocene should be written. Concept introduction: An empirical formula describes the ratio of simplied whole-number of atoms contained in a molecule. The molecular formula tells exact number of each atoms foumd in a molecule. The steps to determine empirical formula are as follows: Divide mass of element by its molar mass to convert mass to moles as follows: Amount ( mol ) = ( Given mass ( g ) ) ( 1 mol No . of grams ) Number of moles thus calculated is written as subscript of element’s symbol and this results in a preliminary empirical formula. In order to convert the moles to the whole number subscripts, each subscript is divided by the smallest subscript. Sum of the product of molar masses times number of corresponding atoms results in empirical formula mass.

Interpretation Introduction

Interpretation:Empirical formulafor ferrocene should be written.

Concept introduction:An empirical formula describes the ratio of simplied whole-number of atoms contained in a molecule. The molecular formula tells exact number of each atoms foumd in a molecule.

The steps to determine empirical formula are as follows:

Divide mass of element by its molar mass to convert mass to moles as follows:

Amount(mol)=(Given mass(g))(1 molNo. of grams)

Number of moles thus calculated is written as subscript of element’s symbol and this results in a preliminary empirical formula.

In order to convert the moles to the whole number subscripts, each subscript is divided by the smallest subscript.

Sum of the product of molar masses times number of corresponding atoms results in empirical formula mass.

Give the structure(s) of the product(s) the reaction below, and be sure to indicate any relative stereochemistry (you can assume that each of the Diels-Alder reactions will proceed with endo selectivity). Draw out relevant enantiomer(s) if they are expected to form. If no reaction is expected to occur under the indicated conditions, then write "no reaction" or NR, and explain why you would expect nothing to occur. If more than one product is formed, please indicate which one will be the major product or if they will be formed in equal amounts. In all cases, equimolar amounts of both components/reagents are present unless indicated otherwise I'm struggling to see how this reaction will go! I am wondering if it will cycle on itself but I'm not sure how I drew out a decagon but I'm a bit lost
