Question
Graph g[n]. Verify with the MATLAB conv function. g(n) = (u[n + 1] - u[n - 2]) * sin (2 pi n/9) g[n] = (u[n + 3] - u[n - 4])* (u[n + 3] - u[n - 4]) * 14[n] Which of the following alkanes has the highest boiling point? propane; butane; pentane; hexane which of the following alkanes has the highest boiling point? 2-3-dimethylbutane; 2-methylpentane; 3-methylpentane; hexane Which of the following can adopt a chair conformation in which there are no axial methyl groups? 1,1-dimethylcyclohexane; cis-1,2-dimethylcyclohexane; trans-1,2-dimethylcyclohexane Which of the following compounds can adopt a chair conformation in which there are no axial methyl groups? cis-1,2-dimethylcyclohexane; cis-1,3-dimethylcyclohexane; trans-1,3-dimethylcyclohexane; cis-1,4-dimethylcyclohexane What is the appropriate dihedral angle between the two methyl groups in cis-1,2-dimethylcyclohexane (Enter the numerical value only, without any units)? What is the approximate dihedral angle between the two methyl groups in cis-1,2-dimethylcyclohexane (Enter the numerical value only, without any units)? What is the approximate dihedral angle between the two methyl groups in the diaxial conformation of trans-1,2-dimethylcyclohexane; 2,2,3,3-tetramathylbutane How many moles of molecular oxygen(O2) are consumed in the complete combustion of one mole of octane(C5H18) (Enter the numerical value only, without any units)? How many moles oxygen (O2) are consumed in the complete combination of one mole of pentane (C5H12)(Enter the numerical value only, without any units)?Explanation / Answer
boiling point increases with increase in no.of carbons hexane has maximum boiling point A straight-chain alkane will have a boiling point higher than a branched-chain alkane due to the greater surface area in contact, thus the greater van der Waals forces, between adjacent molecules. hexane has highest boiling point trans-1,2-dimethylcyclohexane...in all others, one methyl is always axial, one is always equitorial... cis-1,3-dimethylcyclohexane.....same argument as above 2,2,3,3 tetramethylbutane has lowest boiling point....A straight-chain alkane will have a boiling point higher than a branched-chain alkane due to the greater surface area in contact, thus the greater van der Waals forces, between adjacent molecules. 17 in case of octane 11 in case of pentane
