First you should know that as density increases , refrective index also increases. So, it means refrective index is directly proportional to density of substance.
Now, come to second point.
With increase in number of carbon in straight chain in alkane , density also increase with increasing number of carbon atom.
As a combined effect of both of the above points ,
As the number of carbon atom in straight increases, density also increase, therefore refrective index also increases.
With an increase in straight chain alkanes (more carbons present), there will be a linear relationship...

I If you have an alkane and an alkenes with the same number of carbons (and no rings), what is the relationship between the number of hydrogens present on the two molecules, i.e., how do the molecular formulas differ? If you have an alcohol and an aldehyde (or ketone) with the same number of carbons (and no rings), what is the relationship between the number of hydrogens present on the two molecules, i.e., how do the molecular formulas differ? If...
Intro to Stats Q1: Q2: [3-6] Correlation is a measure of the direction and strength of the linear (straight-line) association between two quantitative variables. The analysis of data from a study found that the scatter plot between two variables, x and y, appeared to show a straight-line relationship and the correlation (r) was calculated to be -0.84. This tells us that there is little reason to believe that the two variables have a linear association relationship all of the data...
Question 6 (10 marks) Finally, the researcher considers using regression analysis to establish a linear relationship between the two variables – hours worked per week and yearly income. a) What is the dependent variable and independent variable for this analysis? Why? (2 marks) b) Use an appropriate plot to investigate the relationship between the two variables. Display the plot. On the same plot, fit a linear trend line including the equation and the coefficient of determination R2 . (2 marks)...
A) Assume a linear relationship between the variables Y and X , and that Y is the variable measured on the vertical axis while X is the variable measured on the horizontal axis. A straight line describing this relationship has a y-axis intercept of 45 and a slope of 2. What is the equation for this line? B) Is the relationship between Y and X positive or negative? How can you tell just by looking at this equation? C) Based...
29. What is the relationship between the price of a straight bond and the price of a callable bond? (a) (b) The straight bond's price will be higher than the callable bond's price for low interest rates. The straight bond's price will be lower than the callable bond's price for low interest rates. There is no consistent relationship between the two types of bonds' prices. The straight bond and callable bond will have the same price. (c) 30. The basic...
Part II. Competing nucleophiles with t-butyl alcohol 1. The composition of the product mixture is analyzed based on refractive index measurem. At 20.0 °C, the refractive index of puret-butyl chloride is 1.3877 and that of pure 1-buty bromide is 1.4280. One previous student determined the refractive index of his product mixture to be 1.4250 at 20.0 °C. Assume a linear relation between the refractive index and the molar composition of the mixture. Calculate the molar percentages of t-butyl chloride and/-butyl...
There is a linear relationship between the number of chirps made by the striped ground cricket and the air temperature. A least-squares fit on some data collected by abiologist gives the model y(hat) = 25.2 = 3.3x, 9<x<25, where x is the number of chirps per minute and y(hat) is the estimated temperature in degrees Fahrenheit.What is the estimated increase in temperature that corresponds to an increase of 5 chirps per minute?(a) 3.3 Fahrenheit(b) 16.5 Fahrenheit(c) 25.2 Fahrenheit(d) 28.5 Fahrenheit(e)...
