Draw a dot-cross diagram of Chlorine Triflouride, and discuss the shape exhibited by the molecule

(Drawing cannot be put into this area). The shape of this molecule is influenced by the bonding regions and lone pair regions (lone pairs repel more than bonded pairs). The molecule has 2 lone pairs and 3 bo...

Predict the boiling points (lowest to highest) of Butan-1-ol, 2-methylpropane and Butane

Butan-1-ol will have the highest boiling point of all 3 as it has Hydrogen bonds acting between molecules. This occurs due to the presence of the electronegative O atom. 2-methylpropane is a branched version...

Why is phenol more easily nitrated than Benzene?

This is due to the -OH phenol functional group, which makes nitrating the molecule easier. Benzene has a delocalised pi-system above and below the plane of the molecule. The result of this is that: it is att...

Describe and explain the structure of Benzene

Benzene has a planar structure with a bond angle of 120. The bonds between the carbon atoms in the ring are identical in strength and length. The length of the carbon-carbon bonds in benzene is intermediate,...

An iron-alloy nail (2.41g) is dissolved in 100cm3 acid. 10cm3 portions of this solution are titrated with KMnO4 (0.02M) and 9.80cm3 of KMnO4 was needed to react with iron solution. What % of iron by mass is in the nail?

This is a common example of a titration calculation which can be broken down into several key steps:1) Write a balanced equation for the redox reaction:MnO4 - + 8H+ + 5Fe2+ --> Mn2+ + 4H2O + 5Fe3+(This eq...
