The video tutorial explores the intermolecular forces present in hydrogen cyanide (HCN). It begins by confirming that HCN is not an ionic compound and lacks ions. The tutorial then examines the polarity of HCN using its Lewis structure, highlighting the linear arrangement and electronegativity differences that make it polar. The video identifies the presence of dipole-dipole and London dispersion forces in HCN, noting the absence of hydrogen bonding due to the hydrogen atom being bonded to carbon. The tutorial concludes with a summary of the intermolecular forces in HCN.
